rewritten url is parsed again

[icey]

Hi, I'm rewriting a dynamo url into a static one, but find that even with the last (L) directive, it still parses, seemingly because the url is rewritten and therefore "new" to the processor. i've set up a defensive rule so that it does not check all the conditions (or images!) the second time around, but is it possible to prevent this second parse altogether?

below are the two rules i have, and the rewrite log turned on to 9.

thanks in advance for your help!

httpd.conf
==================
# want to map /zzzzzzzzzzz/blarrrrgh -> /index.php?zzzzzzzzzzz=blarrrrgh

# defense check
RewriteRule!(^zzzzzzzzzzz/.*)$ - [L]

# rewriterule
RewriteRule ^zzzzzzzzzzz/(.*)/$ /index.php?zzzzzzzzzzz=$1 [T=application/x-httpd-php,L]

rewrite log
===============

icey,

Not that I know of. If you change (rewrite) a URL in .htaccess, then Apache must start over from the beginning to "revalidate" it (Check for 404, etc.). Therefore, your "defensive rule" is the commonly-used work-around.

Thanks much! :) I figured it was hopeless, but I thought I'd try. I actually was also concerned about the fact that there are two redirects, but they might be related to a servername redirect. Thanks again!
