Forward HTTP request to different pools based on URI

Hey guys, I'm trying to do something very similar. I saw your iRule example, tried it, but I'm getting a sysntax error:

 

line 2: [wrong args] [string tolower[HTTP::uri]]

 

 

Here's my rule:

 

 

when HTTP_REQUEST {

 

switch -glob [string tolower[HTTP::uri]] {

 

"/start*" { pool zero-new_http-pool }

 

"/*" { pool zero_http-pool }

 

}

 

}

 

 

Any ideas?

 

 

Thanks!
