However, note that each source FILE will be compiled individually into its own assembly, so they cannot have DEPENDENCIES on each other.

A URL is the address of some resource on the WEB, which means that normally you type the address into a browser and you get something back. There are other type of resources than Web pages, but that's the easiest conceptually. The browser goes out somewhere on the Internet and ACCESSES something.

A URI is just a unique string that uniquely identifies something, commonly a namespace. Sometimes they look like a URL that you COULD type into the address bar of your Web browser, but it doesn't have to POINT to any physical resource on the Web. It is just a unique set of CHARACTERS, that, in fact, don't even have to be unique.

URI is the more generic term, and a URL is a particular type of URI in that a URL has to uniquely identify some resource on the Web.

Absolute /Fully Qualified URLs:

• Contain all information necessary for the browser(or other client program) to locate the resource named in the URL
  
  • This includes protocol MONITOR used( i.e http://, FTP://..etc..), Server's Domain NAME or IP address and the file path

• Only provide information necessary to locate a resourcerelative to the current document(document relative) or current server or domain(root relative)

Src attribute means you deploy the source CODE files and everything is COMPILED JIT (just-in-time) as needed. Many people prefer this since they don't have to manually worry about compiling and messing with dlls -- it just works. Of course, the source is now on the SERVER, for anyone with access to the server -- but not just anyone on the web.

CodeBehind attribute doesn't really "do" anything, its just a helper for VS.NET to associate the code FILE with the aspx file. This is necessary since VS.NET automates the pre-compiling that is harder by hand, and therefore the Src attribute is also gone. Now there is only a dll to deploy, no source, so it is certainly BETTER protected, although its always decompilable even then.

Your ISP must first create an IIS APPLICATION and apply the Front Page Server EXTENSIONS to it. Then in Visual Studio.NET, SELECT the "Project | Copy Project" menu. Then enter the URL and select the FrontPage web access METHOD. The "Copy Project" feature copies all of the NECESSARY files to your ISP's machine for your ASP.NET application to run.

You can also FTP your files to your ISP web server. But you must know which files to upload.

Server.Transfer preserves the current page context, so that in the TARGET page you can extract values and such. However, it can have side effects; because Server.Transfer doesnt' go through the browser, the browser doesn't update its history and if the user clicks Back, they go to the page previous to the source page.
Another way to pass values is to USE SOMETHING like a LinkButton. It posts back to the source page, where you can get the values you need, put them in SESSION, and then use Response.Redirect to transfer to the target page. (This does bounce off the browser.) In the target page you can read the Session values as required.
