Problem with WebDynpro using ReverseProxy

[manuel-jeremy_schaffner]

When calling a WebDynpro-Application through a ReverseProxy (mapping e.g. https://portal.intranet.company.ch to https://portal.ssl.company.ch) the first screen of the application can be called, but nothing happens when clicking on any of the controls/links or the message "500 Internal Server Error: The Web Dynpro Application 'xyz' has expired. Please restart the application either with the refresh button or click the following link xyz." appears.

Anybody has the same problems, any ideas why or how to solve it?

See OSS-Note <a href="https://service.sap.com/sap/support/notes/839969">https://service.sap.com/sap/support/notes/839969</a>

For EP6.0 you could use a Reverse Proxy Filter: <a href="https://service.sap.com/sap/support/notes/791080">https://service.sap.com/sap/support/notes/791080</a>

With NW04 all links in J2EE/Portal (inlcuding WD) should be relative and thus also WD should work through Reverse Proxies

Hi,

The problem seems to be because of the reason that the web dynpro application is throwing some exception and the navigation fails and asks you to restart the application.

Check the code.

Hi Mahesh,

the applications work fine when calling them directly in the Intranet. The errors occur when calling them through ReverseProxy from the Internet.

Some WebDynpro-Applications show the first screen and stop interacting then, others (like the SAP WebDynproExplorer) show the error-message mentioned after clicking on a control. I guess that there is some problem with the JavaScript generated by WebDynpro (fixed paths,..), when using it throug ReverseProxy.

regards,

Manuel
