    I am unable to update my original post. Here is an updated version.

    If you simply want to mask URL's then apply a STREAM profile with the following iRule.

    when HTTP_REQUEST {
  log local0. "..in HTTP_REQUEST"

   no replacement for requests
  STREAM::disable
   disable compression server side
  HTTP::header remove "Accept-Encoding"
}
when HTTP_RESPONSE {
  log local0. "...in HTTP_RESPONSE"

   only replace text content
  if {!([HTTP::header value Content-Type] contains "text")}{ return}

  set search ""
  foreach pair [class get myclass] { 
    set search "$search@[lindex $pair 0]@[lindex $pair 1]@"
  }
  log local0. "String replace=$search"
  STREAM::expression $search
  STREAM::enable
}

    Then create a string data class myclass as follows...

    Name                                      Value
/secureapp/connect/report_en/REP   /en
/peter                             /pan

    And get the following output from a logs

    Rule /Common/myrule : ...in HTTP_REQUEST
Rule /Common/myrule : ...in HTTP_RESPONSE
Rule /Common/myrule : search=@/secureapp/connect/report_en/REP@/en@@/peter@/pan@

    And the resulting web page...

    It works!

/en
/pan
