Subject Re: mod_rewrite - Server load?
Date Thu, 07 Mar 2002 07:04:49 GMT

that depends on how many rules there are and what they're doing.
Everything that launches a subrequest - "RewriteCond (.*) -U"  e.g. - will
certainly slow down the server's performance. The same will happen, when you
try to apply a shortname mapping by writing one rule for each shortname, 
instead of
using the "RewriteMap" feature. Omitting the magic [T=text/html] fro 
rules that
will only apply to html will have the same impact.

But these are just my own experiences. Some more elaborated words you'll 
find at:

so long
