A really strange POST problem
Hi.
I'm not sure if this a modperl problem but I'm using modperl (5.005), Apache (1.3) under
Debian on my website.
Using read(STDIN, $ENV{...}, $buffer) to retrieve the post data. At several places i'm using
forms with radio buttons from -2 to 2, but from some of my visitors I got almost randomly
numbers in the form data xxx=13 xxx=4 etc from the radio buttons. I can read these wrong
values directly in the $buffer string. This happen often if they post many times but seems
to be to other visitors also.
I hope I'm not the only one in the world that has this problem...
kind regards
Tomas

Please use CGI.pm, Apache::Request, or something else other than rolling
your own solution for reading the CGI data - it will save you time in the
long run.
If it was a bug you'd have to be more specific as to which versions you
are running of Apache/mod_perl.

Ummm, not sure, but that seems to be the classical problem of not initialicing
the variables at the beggining of the script. Mod_perl mantains a copy of the
value and each time you submit you add the new value to the existing value.
You
are getting different values each time, depending of the httpd child that
serves the script.
Are you using strict (use strict) at the beggining of the script?
