  when HTTP_REQUEST {  
    
      Read in everything after the first / that is not a /. 
      Save that to $session_id and everything else to $uri_to_save  
     scan [HTTP::uri] {/%[^/]%s} session_id uri_to_save  
    
      Rewrite the URI without the session ID  
     HTTP::uri $uri_to_save  
  }  
  

Here is an example:

% set uri /my_session_id_string/path/to/preserve?query=string

/my_session_id_string/path/to/preserve?query=string

% scan $uri {/%[^/]%s} session_id uri_to_save

% puts $uri_to_save

/path/to/preserve?query=string

% puts $session_id

my_session_id_string
