It looks like your rule should work to rewrite just the path (and preserve the query string). Can you add some logging to check? 

 
 when HTTP_REQUEST { 
  
    log local0. "[IP::client_addr]:[TCP::client_port]: Original [HTTP::method] request to [HTTP::host][HTTP::uri]\ 
       with path [HTTP::path] and query [HTTP::query]" 
  
    if { [string tolower [HTTP::host]] equals "www.abc.com" } { 
       if { [HTTP::path] equals "/"} { 
          HTTP::path "/en-CA/default.htm" 
       } 
    } 
 } 
 when HTTP_REQUEST priority 501 { 
    log local0. "[IP::client_addr]:[TCP::client_port]: Current: [HTTP::method] request to [HTTP::host][HTTP::uri]\ 
       with path [HTTP::path] and query [HTTP::query]" 
 }

The second HTTP_REQUEST event allows you to log any changes without having any problems with cached HTTP command output.
