how multiple web servers work for one website?

THey use a product called a "load balancer" that distributes the http requests across multiple servers.  You can also do this with round-robin dns.

It depends on the DNS name of the site you are connecting to. Some sites alias www.site.com and site.com... so either address would work. However, if the site only registers www.site.com, then site.com won't work.\n\nSo, it all depends on what the owner of the site registered as their DNS name.\n\nCheers :)

Virtual servers allow you to partition a physical server.  Instead of running a single operating system, you can run multiple operating systems at the same time.  Mainframe computers have been able to do this for years.  \n\nThe reasons you might want to do it include requirements of a specific piece of software you have to run (maybe a billing system that only runs on a LINUX/Unix kernal, or an older application incompatible with newer OSs), a need to simulate another environement for testing (maybe you have a virtual e mail server, virtual workstation, and virtual web server all together), and others.  It really just depends on your specific need.\n\nThat said, it does not get you the horsepower you would get out of having another real physical server.  You're simply dividing up some of the CPU cycles, Memory, HD space, etc among the different processes.

This is a multi-threaded server.  Much like a web server could do.\nFor comparison, the previous slide is a single threaded server.\n\nThe loops you are interested in are act as such.\nThe server starts and waits for a connection request from a client.  (Upper right yellow box).\nNext: Someone (like you or me) starts our client application (browser) which connects to the awaiting server.  (Dotted line that enters under the upper right yellow box).\nWhen the accept(...) happens, server creates a 'socket' (not shown).  This server fork() 's off (creates) a thread (process) [center right yellow box] that accepts the socket (not shown) and uses the socket to open an input and output channel which connects to the client (not shown).  This whole thing is generally a very fast operation.  That action is done for this client, so it loops waiting for another client to connect.\n\nBack to the client.  Remember, the last thing the client did was connect to the server.  Now the client wants to make a request (write() ) to the server for information.  This is the left yellow box.  It 'requests' and the server 'read()' the request.  Processes it, write() the response back to the client which read()'s the message and does what it needs to do.\n\nThe Client yellow box, and lower Server (client server) yellow box keep repeating (that's the loops) until the client is finished with all its requests.  A good client may send a 'bye' message to the server, so it can cleanly exit.  Other times just having the client exit, drops the I/O connection to the Server thread, which recognizes that action as the client exited, and that server thread exists.\n\nHope this helps.\n=mike

that depends on what webserver you want to use.\nit ur using tomcat it is as simple as \n\nnext > next > next > finish

you would have to query the other website, get its output and write out to the RESPONSE part.\nBasically you would create something like a HTTPWebRequest which would request the page from the server, and then return to client, however please note that this might cause a delay in response as each request will go to the other server from your server before returning the response to the client.

An application server is a server computer in a computer network dedicated to running certain software applications. The term also refers to the software installed on such a computer to facilitate the serving (running) of other applications.\n\nApplication server products typically bundle middleware to enable applications to intercommunicate with various qualities of service — reliability, security, non-repudiation, and so on. Application servers also provide an API to programmers, so that they don't have to be concerned with the operating system or the huge array of interfaces required of a modern web-based application. Communication occurs through the web in the form of HTML and XML, as a link to various databases, and, quite often, as a link to systems and devices ranging from huge legacy applications to small information devices, such as an atomic clock or a home appliance.\n\nPortals are a very common application server mechanism by which organizations can manage information. They provide a single point of entry for all users, they can access Web services transparently from any device, and they are highly flexible. Portals can work inside or outside of the organization, and they can attach themselves to any part of it.\n\n\n\nThe term Web server can mean one of two things:\n\nA computer that is responsible for accepting HTTP requests from clients, which are known as Web browsers, and serving them Web pages, which are usually HTML documents and linked objects (images, etc.). \nA computer program that provides the functionality described in the first sense of the term\n\nAlthough Web server programs differ in detail, they all share some basic common features.\n\nHTTP responses to HTTP requests: every Web server program operates by accepting HTTP requests from the network, and providing an HTTP response to the requester. The HTTP response typically consists of an HTML document, but can also be a raw text file, an image, or some other type of document; if something bad is found in client request or while trying to serve the request, a Web server has to send an error response which may include some custom HTML or text messages to better explain the problem to human people (people trying to fetch a web page, etc.). \nLogging: usually Web servers have also the capability of logging some detailed information, about client requests and server responses, to log files; this allows the Webmaster to collect statistics by running log analyzers on log files. \nIn practice many Web servers implement the following features too.\n\nConfigurability of available features by configuration files or even by an external user interface. \nAuthentication, optional authorization request (request of user name and password) before allowing access to some or all kind of resources. \nHandling of not only static content (file content recorded in server's filesystem(s)) but of dynamic content too by supporting one or more related interfaces (SSI, CGI, SCGI, FastCGI, PHP, ASP, ASP .NET, Server API such as NSAPI, ISAPI, etc.). \nModule support, in order to allow the extension of server capabilities by adding or modifying software modules which are linked to the server software or that are dynamically loaded (on demand) by the core server. \nHTTPS support (by SSL or TLS) in order to allow secure (encrypted) connections to the server on the standard port 443 instead of usual port 80. \nContent compression (i.e. by gzip encoding) to reduce the size of the responses (to lower bandwidth usage, etc.). \nVirtual Host to serve many web sites using one IP address. \nLarge file support to be able to serve files whose size is greater than 2 GB on 32 bit OS. \nBandwidth throttling to limit the speed of responses in order to not saturate the network and to be able to serve more clients.

You need to do that using a server script language, If you want to use it on a web site.\nCGI, PERL, PHP....

web server is a computer with ISA server  or apache ,.... on it.you can put your website (for example html files) on it and make a virtual directory and refer it to there.then people on that network can go to your web page : http://computername/default.html\napplication server is a place to put your other data that network users connect to them and use those data in their programs\ngo to your browser or run : &#92;&#92;computername

you need to run the applications on the PC you consider as server, give it IP address then tell your DNS that this name map to this IP.\n\nopen ports for "others" that the applications will recieve requests through.\n\ntry to connect from one computer to the server.\n\nHave Fun!

In other words the internal clients can't get to the web page.   Are they going to the page via IP address or URL?  If it is URL then you have a DNS problem.  You do have DNS running correct?  You need to put a DNS A record in for the website you have running.

Continued from IIS 5.1 - Installation \nIn order to go configure your website, you need to go:  \n\nStart -> Settings -> Control Panel -> Administrative Tools -> Internet Information Services \n\nIt's a good idea to make a desktop shortcut to Internet Service Manager since we'll be playing with it a lot. \n\nDouble-click on "Internet Service Manager" and let's get started.  \n\nClick on the name of your computer to see the summary of what's going on with your computer.  In my case, my computer is called "DELL-500SC". Double-click on "Web Sites" in the right pane.  You'll see this: \n\nYou can disable a particular service (Web, FTP, or SMTP) by right clicking on the service and choosing "pause" or "stop".  \n\nYou'll notice under "IP Address" it says "All Unassigned"  This means that all requests to your server will be answered by your computer.  If for some reason your server has several IP addresses, you will want to specify the exact IP address that the Internet Services is supposed to respond to.  \n\nIf your computer only has 1 IP address, we can leave the IP address as "All Unassigned".  \n\nLet's take a look at the Web Service.  Right click on "Default Web Site" then select "Properties".  \n\nSince there are so many options I'll just hit the major points. \n\nTab: Web Site  \nDescription - Can be changed to your liking  \nIP Address - Can leave as "All unassigned" or the specific IP address of your computer.  \nTCP Port - 80 is the standard and should remain that way unless you have a good reason to change it.  \nConnections - Although it doesn't say so, we are limited to 10 concurrent web connections.  Each visitor creates 2-3 connections so this means your webserver using this software is limited to 3-4 concurrent visitors which should not be a problem for a small website.  \nTab: ISAPI Filters \nTab: Home Directory  \n\nLocal Path - This is where your files for your website reside.  Please change this to something else.  Many hackers will attack the default directory.  You can change this directory to whatever directory you like, but DO change it.  \nWrite - Unless you want your visitors to actually change your website, you must leave this unchecked.  \nDirectory Browsing - If you check this box, When a visitor comes to a directory that does not have a default document, the visitor will see an error message stating that they are not authorized to view the contents of that directory.  If you uncheck this box, they will get a complete list of what files you have in the directory.  It is best to leave the box unchecked.  \nTab: Home Directory  \n\nLocal Path - This is where your files for your website reside.  Please change this to something else.  Many hackers will attack the default directory.  You can change this directory to whatever directory you like, but DO change it.  \nWrite - Unless you want your visitors to actually change your website, you must leave this unchecked.  \nDirectory Browsing - If you check this box, When a visitor comes to a directory that does not have a default document, the visitor will see an error message stating that they are not authorized to view the contents of that directory.

It depends on what kkind of service you want. In general if you have the necessary software installed on the linux server or any other server whatsoever you can serve any other OS. This intermediate s/w takes care of the necessary translations.\nFor eg you can use "Samba" for file sharing b/w linux server and windows client.\nMost of the http servers around the world use Apache ususally run on linux/unix systems. \n\nMany serveres around the world run on unix/linux. THey provide many services like DNS,DHCP etc to clients running any OS.

You should use Linux, Windows 2000, Windows Server 2003 to run a website(s). You can use XP Pro with Microsoft Information Server. Linux can use Apache or other linux based webservers. There are other third-party webservers for Windows systems.\n\nGet a fixed IP address and a commercial DSL/Cable package. Do not use the web server PC for anything else. Get a battery back-up as well.\n\nAbyss is pretty simple. If you need more advanced controls for end users get ready to invest some money. You would be better off as a web reseller.\n\nCheck out www.serverwatch.com for the latest on ftp, mail and web server software.

I think this is called "hot-linking" and most of the public servers doesn't allow this.\nJust imagine i build a page (my_domain.com/subdir/frame1.html) that loads your page (domain.com/subdir/page1.asp) into my frame. Man! it's your page, and I'm stealing not only your content, but also your bandwidth.\nThat's the reason why it's not allowed.
