Instead of using using webservers I prefer to have some virtual servers running on a 2nd BIG-IP that will respond like webservers.

The replies are send by an iRule like this:

when HTTP_REQUEST {
  set cookielist ""
  foreach cookieinfo [HTTP::header values "Cookie:"] {
    append cookielist [string map -nocase {"; " "<br/>"} $cookieinfo]
  }
  if {[HTTP::cookie exists TestSessionID]} {
    set sessionid "TestSessionID=[HTTP::cookie value TestSessionID]"
  }
  else {
    set sessionid "TestSessionID=[format %09d [expr int(rand()*1e9)]].[format %09d [expr int(rand()*1e9)]]"
  }
#  use standard color names, i.e. "Blue", "Red", "Green", "Yellow", "Brown", "White", "Magenta", "Pink", "Gray"
  set servercolor "Blue"
  
  if {[string tolower [HTTP::uri]] starts_with "/text"} {
    
    set page \
"Server

  } else {
    set page \

  }

  event disable
  return
}

This one can easily be enhanced to mirror different request parameters.

It works as well for cURL with plain text replies:
