  1. WebCat 4.0.1 HTTP_REFERRER over 255 char bug (John Peacock 2000)
I have checked and the instances of GPF's I am seeing do include longer than 255 character referrers (the example I submitted through your bug- tracking software was 310 characters). Since this is a buffer overflow issue (probably) can we expect a quick fix? Also, I came in this AM and found that the system was incommunicado (webcatservice was running but all pages served through WebCat yielded 500 Error's). I have turned on debug logging again... ;~(John PeacockWebDNA Support wrote: > > >And where is it located for NT?
