Multiple RewriteRules for single RewriteCond in .htaccess

by

You can use the RewriteRule flag S|skip to tie multiples RewriteRules to a single RewriteCond (or to a set of RewriteConds). Here is an example that applies one Cond to three Rules:

RewriteCond  %{HTTP_HOST}  !^www.mydomain.com$
# skip rules if NOT within domain - only way to tie multiple rules to one cond
RewriteRule  .?  -  [S=3]
RewriteRule  ^path1(/.*)$  /otherpath1$1
RewriteRule  ^path2(/.*)$  /otherpath2$1
RewriteRule  ^path3(/.*)$  /otherpath3$1

To change an existing Cond to work for multiple Rules you have to:

  • Negate the condition (prepend it with !)
  • If you have multiple RewriteConds:
    Change logical ANDs in the Conds to ORs and vice versa.
  • Add a skipping rewrite rule in front of all rules that you want to tie to the condition(s). Set the S parameter to the number of Rule lines to be skipped.

Please be aware that it is not possible to use any backreferences that point back to the RewriteCond (like %1) in the skipped Rules. These are only accessible in the skipping RewriteRule.
