matching numbers patter in a url

I need to match below patter in a url and re-direct traffic.

 

 

http://www.abc.com/temp/2011/12/temp.html

 

 

Am using below code

 

 

if { [string match {*/*[0-9]*/*[0-9]*/* } [HTTP::uri] } {

 

user pool pool1

 

}

 

 

when run config sync to peer, i get an error saying invalid argument.

 

 

if i escape the special characters like

 

{\*\/\*[0-9]\*\/\*[0-9]\*\/\*} config sync run sucessfully but the url patter does not match.

 

 

Any ideas , am ok not using string match if there's a better alternative.

 

 

thanks.
