server_url=

Tests if a portion of the URL used in server connections matches the specified criteria. The basic 

server_url=

 test attempts to match the complete possibly-rewritten 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 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.

This set of tests match against the requested URL, taking into account 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, the 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.

The 

server_url=

 condition is identical to 

url=

, except for the lack of a 

define server_url

 condition 

and 

[server_url]

 section. Most optimization in forwarding is done with 

server_url.domain

 

conditions and sections.
