Hi all,
We at SUPSI are ready to publish the Helidem portal [1], but we can't
figure out an error that seems happen randomly.

Testing on my workstation it never happened. Others noticed this error
often, then starting browsing in Anonymous Mode the exception disappear.

<?xml version="1.0" encoding="utf-8"?>
<ows:ExceptionReport xmlns:ows="http://www.opengis.net/ows/1.1" xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance" xmlns:xlink="
http://www.w3.org/1999/xlink" xsi:schemaLocation="
xml:lang="en-US" version="1.1.0">
  <ows:Exception exceptionCode="InternalError">
    <ows:ExceptionText>*Unable to read your session file.*

The ZOO WPS is accessible (with basic authentication for now) on a virtual
machine proxied with Apache2 (mod_proxy).

- What kind of information are necessary to ZOO WPS for creating a session
- Maybe this is a browser related issue?
- Maybe a ZOO WPS configuration issue?
- Maybe Apache with mod_proxy?

Any help will be greatly appreciated.. [?]
