Mar 31 01:44:33 wurtel wwwoffles[2250]: Directory 'http/groups.yahoo.com' does not exist [No such file or directory]; creating one. Mar 31 01:44:34 wurtel wwwoffles[2250]: Server has used 'Content-Encoding: deflate'. Mar 31 01:44:34 wurtel wwwoffles[2250]: Cache Access Status='New Page'. Mar 31 01:44:34 wurtel wwwoffles[2250]: Error reading reply body from remote host [zlib: unknown compression method]. Mar 31 01:44:34 wurtel wwwoffled[2246]: Child wwwoffles exited with status 0 (pid=2250). It's a bit late now :-) So I don't have the time right now to investigate. However, a couple of things: - mozilla displays an empty page. I checked mozilla's own cache, and there's a gzipped file with zero bytes there, so it looks like it indeed doesn't get any data whatsoever. - In the wwwoffle cache directory http/groups.yahoo.com there's a file with the wwwoffle error message for not being able to decompress the data received. So why didn't mozilla get this... - Putting wwwoffle offline at this point and reloading in mozilla displays the error message that was in the wwwoffle cache. So why didn't wwwoffle feed that to mozilla when it was online? Perhaps the compression confusion led to wwwoffle feeding the error message to mozilla uncompressed but flagged as being uncompressed (or vice versa)? - Testing with lynx displays the real page just fine... I had expected that the compression between wwwoffle and web server would be independent of whether the client requested it or not?! - Now putting wwwoffle offline and reloading in mozilla again shows only a blank page, even though the log says "Cached Page Used", giving the impression that mozilla should show the same as what lynx did.
