How to use a Datagroup of URI Strings to compare and select pool based on HTTP :: Path

HI ,

 

I have a scenario , I am trying to use do pool selection by comparing the starts_with part of the http::path with consecutive URI included in a Datagroup .

 

More over , when i try to do the compare with http:uri starts_with , I am getting a tcl error with class match .

 

Error :

 

TCL error: /Common/xyz...-irule <HTTP_REQUEST> - bad action "match/a/b/x": must be match, search, lookup, element, type, exists, size, names, get, startsearch, nextelement, anymore, or donesearch   while executing "class match[string tolower [HTTP::path]] equals "URI_datagroup""

 

My condition is the URI startswith /a/b/ is fixed whereas the next part of URI is a variable which can be x or y

 

I have to select the pool based on x or y prior to that /a/b is fixed

    Hi Shripaty,

    This error is caused by no space after "match".

    if { [class match [string tolower [HTTP::path]] equals URI_datagroup] } {

      Thanks , for the hint , but still i am not able to match the consecutive http path with the URI listed in the datagroup

       

      I am trying to match

       

      when HTTP_REQUEST {

       

      if { ([string tolower [HTTP::uri]] starts_with "/a/b") and ([class match [string tolower [HTTP::path]] eq x_URI_list) } {

       

      pool x_pool

       

      }elseif {([string tolower [HTTP::uri]] starts_with "/a/b") and ([class match [string tolower [HTTP::path]] eq y_uri_list]) } {

       

      pool y_pool

       

      }else {

       

      reject

       

      }

       

      }

       

      }

    Can you try this iRule?

    when HTTP_REQUEST {
	if { [string tolower [HTTP::path]] starts_with "/a/b" } {
		set newPath [string map {"/a/b" ""} [HTTP::path]]
		# log local0. "Path without /a/b: $newPath"
		
		if { [class match [string tolower $newPath] equals x_uri_list] } {
			pool x_pool
		}
		elseif { [class match [string tolower $newPath] equals y_uri_list] } {
			pool y_pool
		}
		else {
			# reject
		}
	}
	else {
		# reject
	}
}
