Ability to correlate HTTP response to a HTTP request in iRules

Hi,     We have a requirement to perform certain operations on HTTP response only for specific HTTP requests. Is there any way I can correlate a response to a request in iRules?     Thanks...

Yes, local variables are tied to a connection. Global variables (those set using 'set ::my_var value' in any non-RULE_INIT event or those set as 'set my_var value' or 'set ::my_var value' in RULE_INIT) are available across all connections. SMP summarized this nicely in this post. It's relevant for v10 and v11.

 

 

v10 - local vs. global vars
