url=
Tests if a portion of the requested URL matches the specified criteria. The basic url= test attempts to
match the complete request URL against a specified pattern. The pattern may include the scheme,
host, port, path and query components of the URL. If any of these is not included in the pattern, then
the corresponding component of the request URL is not tested and can have any value.
Specific portions of the URL can be tested by applying URL component modifiers to the trigger. In
addition to component modifiers, optional test type modifiers can be used to change the way the
pattern is matched.
Note: This set of tests match against the originally requested URL, disregarding the effect of any
rewrite( ) actions. Because any rewrites of the URL intended for servers or other upstream
devices must be respected by
<Forward> layer policy, the url= triggers are not allowed in
<Forward> layers. Instead, an equivalent set of server_url= tests are provided for use in the
<Forward> layer. Those tests always take into account the effect of any rewrite( ) actions on
the URL.
