function call in .htaccess ?

Hi,

I use something like this:

RewriteRule ^(.*).png$ ../../templates/png_help/$1.png

The links to png in my pages exist to this subdir, but in fact the png are
located somewhere else in a templates directory.
Now, I'm shuffeling folder layout, in part to support localisation etc.
therefore the location might differ based on variables.

Can I use external variables somehow in .htaccess ?
E.g. {TARGET_DIRECTORY}/templates/png_help/$1.png

Or call a function that outputs the directory ?
e.g. <?php echo DIR ?>/templates/png_help/$1.png

or .... ???

Your insights appreciated.

Hi Peter,

If I were you I would repost this in alt.apache.configuration

That will surely not work.
You have no PHP variables available in your apache configuration.

Maybe you can solve this with a rewriterule, but I don't know how.
Alternatively you can simply call a PHPscript that returns the png.

From HTML, instead of:
<img src="templates/png_help/example.png">

you write:

<img src="mypngscript.php?png=example.png">

And let mypngscript.php handle all complex path stuff.

If you do this, don't forget to set the headers correctly.

I had to use the following when generating a .pdf (which I did not want
cached).

header('Content-Disposition: inline; filename="'.$this->pdfFilename().'"');
header('Content-type: application/pdf');
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header('Expires: '.date(DATE_COOKIE,time()-120));
header('Pragma: public');

You can find the correct value for your content-type line in the
mime.types file in your apache configuration directory.
