1. When you execute the query, you must set savequery=true. Mapserver 
will then create a .qy file. Check in your tmp directory to see if the 
.qy file has been created.

2. You must get the name of the query file from mapserver. Something 
like the following will work:
    <input type='hidden' name='queryfile' value='[queryfile]'>

3. With each subsequent form submission, be sure the name is passed back 
to mapserver e.g.:
    queryfile=tc10776330262312.qy
(The above hidden form variable will do this)
