iRule and trailing slash issue

Folks,

 

 

Got a issue that is bugging me. Here is the iRule that I am working off and it works for the most part, but i have to put the trailing "/" for it to work. I need to have it working without the slash at the end.

 

 

when HTTP_REQUEST {

 

if { [string tolower [HTTP::uri]] starts_with "/dev3" } {

 

HTTP::uri [string range [HTTP::uri] 5 end]

 

pool dev3

 

}

 

}

 

 

The dev3 entry is mostly working as long as you remember to include a trailing "/" on the URL -- so https://www.aaa.bbb.com/dev3/ works where https://www.aaa.bbb.com/dev3 does not, it gives a message about a bad request.

 

 

Any ideas?

    With that rule, if the URI was just /dev3, the URI sent to the web app would be null. That's not valid in HTTP. You could use this to check the URI:

    
when HTTP_REQUEST {
   if { [string tolower [HTTP::uri]] starts_with "/dev3" } {
       Set the pool to dev3 for all requests starting with /dev3
      pool dev3
       Remove /dev3 from the URI
      set uri [string range [HTTP::uri] 5 end]
       Check if updated URI has a length
      if {$uri}{
          Updated URI has a length, so set the request to the updated URI
         HTTP::uri $uri
      } else {
          Updated URI was empty, so set the URI to /
         HTTP::uri /
      }
   }
}
