Several sources, for URLs only check out: ftp://www.ics.uci.edu/pub/ietf/uri/rfc1738.txt However, I think you are looking for HTTP URLs, for that check out the HTTP 1.0 specification, specifically section 3.2.2 "HTTP URL" http://www.w3.org/hypertext/WWW/Protocols/HTTP1.0/draft-ietf-http-spec.html < As example, the netscape browser version for windows append the cursor < coordinate to the URL defined in the map file. The netscape browser < version for X-window doesn't react the same, it remplacing the < QUERY_STRING portion of the URL defined in the map file. Suggestion #1: never assume netscape is doing it the standard way, they likely are not. < So, having defined: default /cgi-bin/program/path_info?query_string < < will generate on windows version: /cgi-bin/program/path_info?query_string?x,y < will generate on X-window version: /cgi-bin/program/path_info?x,y From my understanding of HTTP URLs the windows version is wrong, but this is up for interpretation. From there, it just depends upon how 'path_info' handles its arguments. That they should be standard there is no doubt; unfortunately they are not. -Brandon Gillespie-Received on Tuesday, 26 March 1996 12:17:45 GMT
