Build Identifier: Version: 3.6.0.v20100427-9KAjFKvFs-Uz-4QX1m0EdXVS Build id: I20100513-1500

On startup RAP only displays a white page although the full http source has arrived on the client browser.

I have encountered this problem on two occations so far:

The first time when I did secure the url of to the rap application behind sping security filter.
In that case Spring takes me to the login form and after successfull authentication Spring takes me to the originally entered webaddress of my rap application. But instead the rap application I see the white page.

The second time was when I installed a proxy servlet that handled all calls to <ipaddress>:80/rap/examples and gave back the contents it got from calling <ipaddress>:8081/rap/example .
We wanted to do this because of the cross site scripting problem.
In this case I get a white page too.

As far as I understand RAP is sending an initial page to the client to find out if it is capable of displaying RAP and initiating the data communication with the RAP server.

This seems only to work with the original request to display RAP. It seems not to work, if there is some processing between.

Reproducible: Always

Steps to Reproduce:
1. Go to http://dev.mixendo.com/wiki/Mixendo_XHR/
2. Enter 'http://rap.eclipsesource.com/rapdemo/examples' in the URL text field
3. Uncheck 'enable XHR'
4. Press 'Recreate iframe'

Result: an empty page is displayed in the tab 'render response' but the full code is in the tab 'raw response'

Note: you can also reproduce this when redirecting with a proxy servlet.
