Where do you expect it to look?

URLs can be shortened in many ways, when a URL is shortened browsers will
try and make sense of them, and servers will try and interpret what the
browser offers them, but if your browser asks a server for a file it
can't find, you'll get an error (which the browser may hide from you
while it tries something else)

You're obviously having problems understanding how urls relate to files
and servers.

A url such as "http://server/path/file.type" generally means go to the
web server "server" and ask it for "/path/file.type"

In the absence of anything that tells it otherwise in the configuration
file "/path/" usually maps in some fairly literal way to the directory
structure below whatever is configured as DocumentRoot, eg on your
windows machine, where DocumentRoot is (I think) "c:\wamp\www\", then if
"/path/" in the url was "/fred/jim/tony/" your server would be looking in
"c:\wamp\www\fred\jim\tony\" for a file called "file.type", which it
would then process according to any other instructions (such as things
that tell it what to do with ".php" files etc)

Now, a url may get shortened, to, for example "file.type", in which case,
when a browser requests "file.type" because a user has clicked on a link,
the browser will use the path information of the current file to build
the request.

This means that if you're looking at "http://server/joe/sue/file1.type1"
and click a link that was coded as '<a href="file2.type2">some text</a>'
then the web browser logic works something like:

I'm looking at "http://server/joe/sue/file1.type1" and now I want
"file2.type2" so I request "http://server/joe/sue/file2.type2"

and you would expect your server to deliver c:\wamp\www\joe\sue
\file2.type2

However, if the link was '<a href="/file2.type2">some text</a>', the
browser logic works something like:

I'm looking at http://server/joe/sue/file1.type1 and now I want "/
file2.type2" so I request "http://server/file2.type2"

and you would expect your server to deliver c:\wamp\www\file2.type2

The leading slash means "start at the webroot and work down"

There are other ways links can be specified:

".." means "up one directory level"

With '<a href="../alison/file2.type2">some text</a>' the browser logic
works something like:

I'm looking at "http://server/joe/sue/file1.type1" and now I want
"../alison/file2.type2" so I request "http://server/joe/alison/
file2.type2"

and you would expect your server to deliver c:\wamp\www\joe\alison
\file2.type2

and with '<a href="../file2.type2">some text</a>' the browser logic works
something like:

I'm looking at "http://server/joe/sue/file1.type1" and now I want
"../file2.type2" so I request "http://server/joe/file2.type2"

and you would expect your server to deliver c:\wamp\www\joe\file2.type2

Finally, a note of caution. If you use "localhost" or "127.0.0.1" as the
"server" in the urls in web pages on your computer, anyone trying to view
the web pages from from any other computer WILL get errors. If you wish
to specify absolute paths from the webroot, use

'href="http:/path/file.type"'

and not

'href="http://localhost/path/file.type"'

This is because when their web browser process "localhost" or "127.0.01",
it will try and ask a webserver running on their machine for the file
(because on their machine, localhost is their machine) and obviously,
even if they have a webserver running, it won't be using the files from
the DocumentRoot c:\wamp\www on your machine.

This really is outside the scope of comp.lang.php though.

I'm setting followups to comp.infosystems.www.authoring.html
