Has anyone every experienced this problem or do you know of any
possible solutions to it? Please let me know otherwise I'm completely
stuck and will have to recode everything into PHP mostly from scratch.

Subject: [opencms-dev] Responding back to application's HTTP POST
valueswith HttpContentType=application/x-www-form-urlencoded
I am trying to communicate back to an executable (installer file) that
is sending me values via HTTP POST but continue to run into problems
with the HttpContentType being converted back to
"text/html;charset=UTF-8" within OpenCMS 6.2.1.
How do I set my pages's response (HttpContentType) as
"application/x-www-form-urlencoded" and keep it that way. I've tried a
number of different methods but it seems as though OpenCMS is forcing
the HttpContentType to revert back before I can communicate back to the
application by way of out.print("something");
Is this a known problem in OpenCMS 6.2.1? Is there something within the
configuration files that I can do to prevent my attempts to responsd
from being converted back to "text/html;charset=UTF-8".
Thanks in advance.
Here is the code (index.jsp) I'm trying to create the response back to
the application with:
