Re: CSS file not being found -- WEB400

I think some of the confusion is from the old CERN based HTTP server
(remember that? lol).

It didn't really have a DocumentRoot (in the Apache form) and IIR if you
didn't specify a link with a forward slash it would use the "current"
directory of the URI (such as /cgi-bin if you're running a CGI program).

Similar to how directories work with WRKLNK and other IFS type commands,
etc... if you don't use a forward slash, it tacks on the "current
directory". Which means being consistent and never changing the current
directory things will work, but if that does change and you're not
specifying the fully qualified path, then problems and confusion start.

The use of a forward slash (qualified path) just followed through for some
(including me) to the Apache server. I only prefer the forward slash
because it's how I've always done it, and it's never caused me an issue,
even with multiple environments. And I've put together many thousand sites
for myself and many others over the years.

As long as I set up my paths/directories the same for each environment, it
works (and "should" work with a virtual path as well with the Apache
server).

But I HATE seeing things like .../../..//../../main.css in HTML files..
(yes, that's exaggerated).. haha..

I have never used a base tag, but I still use relative links in
dynamically generated HTML. Works just fine.

The browser would only do that if you reset the document base using the

<base> tag. I should have thought of that earlier, because it's (IMO) the
more correct solution to the original problem. However, it's been a while
since I've written a cgi-bin script that produces HTML. ;-)

Example
<head>
<base href="http://my.domain.name/"; />
</head>

It depends on the directives, but normally HTML delivered from a CGI

program (for example) are deemed to be in the document root. So HTML
delivered that way can reference static resources relative to the document
root (without a preceding '/').

It works like that for me anyway :) I never use absolute paths in my

apps. Not sure why, or what is better or worse really. I am sure there
are arguments to be had either way.

I've generally used absolute paths, so it'd help me to know how the

current folder is determined - I thought it was the folder where the active
HTML file is located.

Now if that's true - it's fine for static pages. But dynamic pages are

not located anywhere. So what is the current folder then? Is it the
document root?

I was just looking up some of this but did not get an answer quickly. I

do remember reading about it once upon a time - along with other fairy
tales, eh?

You should not have to put a '/' in front of the file name to make it

work. That just makes it an absolute path. It should would without '/' as
long as the file you are looking for it relative to the current folder.

For example:
/foo/bar/kevin.css
This translates to:
http://www.example.com/foo/bar/kevin.css

But without the slash, it becomes a relative reference rather than

absolute:

foo/bar/kevin.css
tells the server to look in the current folder (not the root folder)

for the directory "foo" and then drill down to "bar" for kevin.css.

../foo/bar/kevin.css
tells the server to go back one folder from the current folder, then

look in directory "foo" and then drill down to "bar" for kevin.css.

So if it doesn't work without a '/', it just means that you are not

referencing it properly, relative to the current folder (i.e. the folder in
which the HTML file resides that is requesting it).

In other words, if I have a directory structure like this:
myserver
-->htdocs
---->css

If my html file is in myserver/htdocs and my css file (called
steve.css) is in myserver/htdocs/css Then my html can reference the
css like this (without a '/' at the start) href="css/steve.css"

If steve.css is in the same place as the html (i.e in myserver/htdocs)

then it can be referenced like this:

href="steve.css"

Clear as mud!

That is what I said in my first reply Steve! :)

I see that now.. Smacks head.

Now that it is working I see that it does not work without the / in

front of the .css file name:

<link rel="stylesheet" href="/steve.css" /> 
<link rel="stylesheet" href="steve.css" /> 

The <directory> directives are mainly for you to dictate permissions
to various locations in the document root. You can refer to anything

in a <directory> directive, but if the directory does not exist, it just
gets ignored.

got it.
