How to disable iRule processing on keep-alive per request when using HTTP::respond

Okay, I submitted my feature request.

 

 

Here is my proposed changes:

 

 

I want to change the syntax for the "event" command.

 

 

Currently syntax is:

 

 
 event [] [enable|disable] | [enable all|disable all] 
 

 

 

I propose that the new syntax would be:

 

 
 event [] [enable|disable|end] | [enable all|disable all|end all] 
 

 

 

And basically, this will change the following scenario:

 

 

Current procedure for disabling an event for a single request:

 

1) CLIENT_CONNECT

 

2) HTTP_REQUEST event HTTP_REQUEST disable

 

3) HTTP_RESPONSE event HTTP_REQUEST enable

 

4) HTTP_REQUEST

 

5) HTTP_RESPONSE

 

6)

 

 

New procedure to get the same exact results:

 

1) CLIENT_CONNECT

 

2) HTTP_REQUEST event HTTP_REQUEST end

 

3) HTTP_RESPONSE

 

4) HTTP_REQUEST

 

5) HTTP_RESPONSE

 

6)

 

 

This is useful for functions like HTTP::respond which causes the BigIP to send a response back to the web client, but the HTTP_RESPOSE event is not being executed.

 

 

Also useful for HTTP::redirect

 

 

 
 rule redirect { 
     when HTTP_REQUEST { 
         if { [HTTP::host] equals "yoursite.com" } { 
             HTTP::redirect http://mysite.com/ 
             event end 
             return 
         } 
         elseif { HTTP::host equals "thatsite.com" } { 
             HTTP::response 200 content { 
                  
                  
                 We have moved to a new domain. 
                  
             } noserver 
             event end 
             return 
         } 
  
         pool mysite.com_pool 
     } 
 } 
 

 

 

In the above code (assuming yoursite.com, thissite.com and mysite.com all resolve to the same IP number for the web browser) the keep-alive connection does not have to end in order to get sent to the mysite.com web site from one of the other URLs.

 

 

Of course this is a primitive example, this is best used in cases that have more advanced and complex uses that require the keep-alive connection to remain open.
