Subject: tomcat form authentication behind proxy  looping issue.
X-Virus-Checked: Checked by ClamAV on apache.org

 Greetings:

I am using Tomcat 5=2E5=2E20 behind an apache 2=2E2 mod=5Fproxy=2E The web=
app uses
form authentication=2E

If I access the webapp directly (http://localhost:8080/mywebapp) the
authentication works and the user is redirected to the homepage=2E

If I access the webapp behind the proxy (http://mywebapp=2Elocalhost) the
authentication works but loops through the authentication process
infinitely until the server times out=2E

I have debugging enabled for the authentication process and I see in the
logs that the user passes authentication and the principal and role are
created=2E The log statements are repeated about 10 times and then in the
browser I get a server timeout message instead of being redirected to the
homepage=2E

Here are the apache2 proxy directives:
=2E=2E=2E
ServerName mywebapp=2Elocalhost
ProxyRequests Off
ProxyPass / http://localhost:8082/mywebapp/
ProxyPassReverse / http://localhost:8082/mywebapp/
RewriteRule ^/(=2E*) http://localhost:8082/mywebapp/$1 [P,L]

Here is the connector element in the server=2Exml
=2E=2E=2E
<Connector port=3D"8082" maxThreads=3D"300" minSpareThreads=3D"25"
maxSpareThreads=3D"75" enableLookups=3D"false" acceptCount=3D"100"
connectionTimeout=3D"20000" proxyPort=3D"80" disableUploadTimeout=3D"true"=
 />


Has anyone seen this type of behavior before with their application=3F Wil=
l
switching to a mod=5Fjk proxy change this behavior=3F Thanks for any insig=
ht
you might have about this=2E

Thanks=2E
Bill=2E=20
