[mh] http server problem

[Steve G. <st...@fa...>]

I have a problem with the weather_graph_zoom script that I can't figure
out. The problem seems to be browser related but it also is mh version
related. Here's what happens, if I bring up weather zoom the first
time it is ok. However if I change a parameter and hit the zoom button
the script blows up. The reason the script blows up is that it
appears the the CGI parsing never happens so the script sees the
form as the param data, e.g. you can see in the http server log:

   bin/weather_graph_zoom.pl ------------0xKhTmLbOuNdArY Content-Disposition: form-data; name="sensor1" tempspare5 --------
   ----0xKhTmLbOuNdArY Content-Disposition: form-data; name="sensor2" nosensor ------------0xKhTmLbOuNdArY Content-Disposition: form-data; name="width" 600 ----
   --------0xKhTmLbOuNdArY Content-Disposition: form-data; name="height" 250 ------------0xKhTmLbOuNdArY Content-Disposition: form-data; name="debmonth" 12 ----
   --------0xKhTmLbOuNdArY Content-Disposition: form-data; name="debday" 11 ------------0xKhTmLbOuNdArY Content-Disposition: form-data; name="debyear" 2005 ----
   --------0xKhTmLbOuNdArY Content-Disposition: form-data; name="endmonth" 12 ------------0xKhTmLbOuNdArY Content-Disposition: form-data; name="endday" 12 -----
   -------0xKhTmLbOuNdArY Content-Disposition: form-data; name="endyear" 2005 ------------0xKhTmLbOuNdArY Content-Disposition: form-data; name="submit" Zoom...
   ------------0xKhTmLbOuNdArY--

rather than something like:

/bin/weather_graph_zoom.pl sensor1=tempspare5&sensor2=nosensor&width=600&height=250&debmonth=12&debday=11&debyear=2005&en
dmonth=12&endday=12&endyear=2005&submit=Zoom...

This happens if use Safari as my browser (mh 2.100 is not running on the mac). If I use
firefox from the mac then weather zoom script works normally. Now the strange thing
is that if I use Safari to connect to a different machine running mh 2.96 then
Safari works fine but to the machine running mh 2.100 it fails.

So I turned on http debugging and there is more strange behavior but probably the
bigger clue. When I run Safari to the machine that fails I see in the log:

Mon 12/12/05 13:20:49 POST /bin/weather_graph_zoom.pl HTTP/1.1  data:POST /bin/weather_graph_zoom.pl HTTP/1.1 Host: wiz:7070 Connection: close Referer: http:
//wiz:7070/bin/weather_graph_zoom.pl User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en) AppleWebKit/312.5.1 (KHTML, like Gecko) Safari/312.3.1 Accept:
*/* Accept-Encoding: gzip, deflate Accept-Language: en Content-Type: multipart/form-data; boundary=----------0xKhTmLbOuNdArY Content-Length: 965

Now what seems to be a clue is that when I use firefox to connect to the mh 2.100 machine
I never see POST in the log. I don't see why Safari is doing a POST. Interestingly if
I use Safari to connect to the mh 2.96 machine I don't see POST but only GET.

I'm sure I could figure this out given sufficient time but since there seem to be
plenty of people on this list with lots of http and cgi experience I'm hoping
they can point out what is going wrong here and how to fix it. Thanks.
