Changeset 18313 for gsdl/trunk/runtime-src/src/w32server

Timestamp:

Message:

Fixed bug to do with initialization of RequestFields variable. Had been using a memset to make it all zero, but this is not a safe thing to do when there are text_t fields in the class. Code upgraded to use a constructor and 'reset' function that explicitly initializes and clears the text_t fields
