Scan header for mdn in irule through regex

Hi,

I did not really understand what you wanted to do or what mdn means

but hope it will help you.

find below a simple irule that allow to retrieve value of header:

when HTTP_REQUEST_DATA {
 
set toheader "tel:+12253941228;tag=MwsjgSMFBd"
 
regexp {^tel:([^;]+);tag=(.*)$} $toheader -> tel tag
 
log local0. "tel: $tel - tag : $tag"
 
}

let me know if you need more details or explain me exaclty what is the wanted result!!!

regards
