source: trunk/gsdl/src/w32server/httpreq.h@ 2286

Last change on this file since 2286 was 2286, checked in by sjboddie, 23 years ago

Had a bit of a tidy up in the fnord webserver code. The main change of note
was the removal of our reliance on the MAX_URL_SIZE constant. URLs and post
data of any length should now work.
