I'm new to this framework and web development in general: I ran across this problem today, and I think it's a bug (and I kinda fixed it), but I'm not sure... Anyway, using Laszlo as a front-end, I tried to post to a url served by tbnl. Couldn't get at the POST data, couldn't get at it, couldn't get at it. Finally, I noticed two things: 1) the header from laszlo for content-type was: "application/x-www-form-urlencoded;charset=UTF-8" 2) in initialize-instance and recompute-request-parameters, the code was: (string-equal "application/x-www-form-urlencoded" (string-assoc "content-type" headers-in)) So I tossed in: (string-equal "application/x-www-form-urlencoded" (string-assoc "content-type" headers-in) :end2 (length "application/x-www-form-urlencoded)) which is not particularly efficient, but is at least correct. Am I wrong?
