I'm getting a bit carried away by this now, and someone needs to stop me

I've applied the same idea to assist with reducing bandwidth

In my .htaccess file I've added this:

  #
  # avatar.php rewriting
  #
  # av1-1053412959.gif = userid + dateline
RewriteRule ^av([0-9]+)-([0-9]+).gif$ avatar.php?userid=$1&dateline=$2 [L]

  #
  # attachment.php rewriting
  #
  # atp157156.gif = postid + extension
RewriteRule ^atp([0-9]+).([a-z]+)$ attachment.php?postid=$1 [L]
  # att157156.gif = attachmentid + extension
RewriteRule ^att([0-9]+).([a-z]+)$ attachment.php?attachmentid=$1 [L]

And you should be able to figure the rest out

Simply change all references of avatar.php?userid=$post[userid]&$post[dateline]... and variations, for av$post[userid]-$post[dateline].gif

Don't worry about the extension, the correct mime-type will be returned by the php... and that's whats important.

Then change template postbit_attachment so that the URL for attachments is this : atp$post[postid].$post[attachmentextension]

Note that this also sidesteps a bug in Mozilla whereby downloading a zip file from a php page would prompt a php file extension rather than zip.

I've been hacking for sure, and again I don't recall clearly every change I made. But if you got the gist of everything else in this thread then I've no doubt you can do this.

Essentially the point is that a lack of querystring allows the browser and proxies/caches to cache the avatars and attachments.

This obviously reduces bandwidth... and also reduces database load.

I have high hopes for this little addition to this very fine hack
