read is blocking on win32 CGI

[William]

Hi,

I'm working on a CGI which invoked by IIS6.0. However, in the cgi perl
script, i have a read which should read all POST content. I found 2
things interesting

1. the read becomes blocking if I want to read more than it was
submitted
2. the $ENV{'CONTENT_LENGTH'} is not reliable. In my case, the content
is 16330 bytes but it tells me 16600.

Anyone see this behavior? How to do non-blocking read in CGI?

thanks,
william

Let me guess, is the file 271 lines long?

Are you using CGI.pm? If not, you should be...
