Have you tried setting JKLogLevel to Debug in the httpd.conf for the 
apache webserver?

What version of Tomcat and What version of Apache?

[users@httpd] Apache / Tomcat questions

Firstly, apologies if this is a  no-brainer - I am newbie to Apache 

I have a perplexing problem:

Our webapp uses Tomcat, and we have recently started to front it with 
The app runs on fedora core 6 and uses the mod_jk 1.2.21 connector and 

We have a problem with POST's on one of our JSP's - this particular JSP 
form is huge - it has over 
100 fields. T

The problem is that the receiving HttpServletRequest object does not have 
some of the request 
parameters when the request is made via http. If the request is made via 
https it works fine.
The params are simply not there at all. Sometimes the parameter values are 
non-printable characters, 
but not always. It doesn't seem to be consistent.

I am pretty sure that Tomcat itself is not an issue, 'cos standalone TC 
works fine.

My feeling is its something to do with either the Apache https / http 
setup or the mod_jk connector.


Has anyone experienced this before?
Is it possibly to get Apache and mod_jk to log the POST header data so I 
can see where its going 
wrong. If, so how do I do that?
