Re: CGI Image on localhost

Typically with apache, you have your cgi's in a sperate directory than you static, non-program, content. You have that straight. What you would typically do is have your images refered as http://machinename/images/image.jpg

You can use .., but you'd probably use ../images/image.jpg. That's a relative url. Relative url's are nice usually, but it's a matter of opinion what people like more :)

Remember, for browsers, its typically nicer to use /'s instead of \'s.

Cheers thats what I was looking for, however will <quote>relative urls</quote> work under windows eviroments e.g. the windows servers??

All in all, apache should do the right thing with slashes.

Here's a long winded explanation on why it's fine...

Let's put it this way. When you click on a link in a browser, it's supposed to issue an http request to the server based on the href. If the href has ../../../ etc, it will strip a few directories in the request. LIkewise if you do ../tmp/../tmp/../tmp. That's basic directory resolving in any os (replace /'s with \'s).

So if you are at http://www/somedir/somedir2 and clicked a link http="../", you'll ask for http://www/somedir , if you clicked http="../somedir2/../somedir2" it should request http://www/somedir2/../somedir2. That is a guess. It may recompress it back to http://somedir/somedir2, but that's somethign to test and play with. not very useful :)

Anyway, the browser should try and compress it somewhat, turning initial ../'s back into something shorter. The request is sent to the server and it can interpret it ANY WAY it wants. Doing something like /cgi-bin/this.cgi/that will pass that as an argument to your this.cgi script. This is a feature of the server 'cause it parses it that way. Well, at least apache did last i checked :) Anyway, last check, apache on windows should translate http://blah/this/../that/ int c:\whereyouinstalledapache\htdocs\this\..\that, which should turn into c:\whereyouinstalledapache\htdocs\that.
