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.

    Hi Puli,

     

     

    Can you try this:

     

     

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

     

     

    Only the square braces should need to be escaped if you wrap the pattern in double quotes instead of curly braces.

    Small problem facing with the match.

     

    Its also matching

     

    http://www.abc.com/temp/barton2011/12/temp.html

     

     

    How can i make it so it only strictly matches number and ignores letter in it ?

     

     

    thanks.

    Can you provide a few more examples of URIs you do want to match a few that you don't?

     

     

    Thanks, Aaron

    Hi aaron,

     

     

    i fixed it, i had a wildcard in front that matching all characters followed by numbers. Below is the modified one

     

     

    From

     

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

     

    to

     

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

     

     

    I had to match only url of specific type

     

     

    http://www.abc.com/temp/[digits]/[digits]/temp.html

     

     

    thanks for the support.

     

    Appreciate it.
