Long Form submitted issues CGI Timeout

External Since: Nov 11, 2005 Posts: 8

Having trouble with long forms in IIS6 (and IIS5). I just tested IIS6
by creating a static HTML page with a large form (196 fields). Here is
the code:

<HTML>
<HEAD>
</HEAD>
<BODY>
FORM TEST<BR><BR>
<FORM METHOD=POST ACTION="formtest.html">
<INPUT TYPE="submit"><BR><BR>
<INPUT TYPE=text NAME="Field_0">
.....
<INPUT TYPE=text NAME="Field_196">
</FORM>
</BODY>
</HTML>

Saved this on our IIS6 server as formtest.html and opened the page.
When I submitted it I got a CGI Timeout. If I cut back the fields to
say 190, it works (as long as I keep the fields empty. if I enter
enough lines of text, it CGI Timeouts as well).

IIS5 has the same issue, but it can handle 379 empty fields (submits
immediately) but not 380 empty fields (CGI Timeout after 5 minutes)

Need some help because many of our forms are longer than this.

> So, I think the problem is either with:

I tried ACTION="formtest.pl" with similar results. formtest.pl is just
a standard perl script. After hitting the submit button, it seems like
the page goes nowhere.

> 2. What ISAPI Filters are installed on the server. Some may be screwing up larger request entity body

NONE

> 3. Is this over SSL or not. This can be problematic if SSL Renegotiated certificates in the middle.

NOT over SSL

Since you don't think its what I described and I have answered you
questions (as best as I can), do you think you can help a newbie like
me with some ideas to try to resolve this issue, i.e. some things that
I can try.
