URI Pool Redirect Question

That looks good. You should either add a OneConnect profile (Click here) to the virtual server or put an else statement in the iRule. Either option would ensure subsequent requests on the same TCP connection are sent to the correct pool based on the iRule logic.

Hi Aaron,

 

Thanks for the quick response and information. I've had a read about OneConnect and we have fairly specific logging requirements at present, I think I'll look at that in more detail in future. I'd like to add the 'Else' statement as you suggest but the web farm I run is not small and we run around 400 domains split accross multiple pools. So www.domain1.com points at pool1 and and www.domain2.com points at pool2 etc. Can I word the 'Else' statement to pass the request to the original pool rather than a specific pool if the condition is not met?

You can get the VS's default pool using LB::server in CLIENT_ACCEPTED, so this should suit your needs:

 
 when CLIENT_ACCEPTED { 
  
     Save the default pool name 
    set default_pool [LB::server] 
 } 
 when HTTP_REQUEST { 
    if { [HTTP::uri] starts_with "/abc" } { 
       pool abc_pool 
    } else { 
       pool $default_pool 
    } 
 } 
 

You can specify a source netmask on a OneConnect profile of 255.255.255.255 to ensure only the same client IP address reuses a server side TCP connection.

I'll test that next week, thanks again.

That works fine though I've modified it slightly as I wasn't dealing with case.

 
 when CLIENT_ACCEPTED {  
  Save the default pool name  
 set default_pool [LB::server]  
 }  
 when HTTP_REQUEST {  
 if {[string tolower [HTTP::uri]} starts_with "/abc" } {  
 pool abc_pool  
 } else {  
 pool $default_pool  
 }  
 }  
 

I'm looking into this now but I have some URL's with /abcd and /abcd.aspx for example that I do not want to redirect, I only want to redirect /abc or /abc/. If someone has a quick answer, please feel free to post. Thanks.

Will this do the trick?

 
 when CLIENT_ACCEPTED { 
  
  Save the default pool name 
 set default_pool [LB::server] 
 } 
 when HTTP_REQUEST { 
 if {[string tolower [URI::path [HTTP::uri] 1 1] equals "/abc" } { 
 pool abc_pool 
 } else { 
 pool $default_pool 
 } 
 }
