Subject Problems Parsing Request Paramers
Date Tue, 27 Sep 2005 17:29:36 GMT
First off, I apologize for the cross-post.  I posted this same message
in the User's mailing list with no replies.   So, my hope is that one of
you developers may have some insight into the problem that I'm having.

Certain users of my website are having issues with respect to submitting
a form on a page.  Not all users are experiencing this problem, and I've
yet to replicate it myself so it makes the situation even more complex.
I have an icking suspicion that its related to the user's browser, but
I've tested on the same browser version/subversion without a glitch.
Here's the scenario:
1) User goes to page.
2) User fills out form.
3) User clicks submit.
4) JSP page then performs sanity checks against submitted data.  In the
event of a failure on the sanity checks, page is redirected back to
previous page.

Simple enough.  Well, users are filling out the form and clicking submit
with valid infromation, yet when I parse the parameters out of the
request, I'm finding none of the form values from the previous page.  I
then decided to investigate further and log out all request information
in the event that these sanity checks fail.  The following is what I
logged out:

------------------------------------------------------------------------
---------------------------------
There are many interesting things about this request.  First, the
content-length is 0.  Not sure how this could happen...error in
browser??  Second, and the most intriguing...Notice the "referer" entry.
The referer entry actually contains all relevant information that I
needed in order to process this request, yet if you look at what
parameters I was actually able to parse off this request you will
see...NONE.

I'm stumped.  Anybody else seen this before?

Environment:
JDK 1.4.2_08
Tomcat 5.5.9
