IIS Forgerock WebAgent 500 HTTP Error from iisWASPlugin_http.dll

Hi everyone,

In our journey with Forgerock. We have an use case we have to protect an application using an IIS Windows Web Server and an Windows Server running two Java Apps hosted with WebSphere Servers.
The IIS Web Server is using iisWASPlugin_http to redirect the request to the right app based on the Path of the request. For example:


The plugin is using the app1 and app2 for filtering the requests to the right website.

We are attempting to access App1 from a bookmarked url exactly → host_com/app1/servlet/LogonServlet

The IIS Forgerock Web Agent gets the request and because we don’t a session, we initiate the Login Journey. After authenticating, we get redirected to host_com/sePlugins/iisWASPlugin_http.dll
with a 500 HTTP Status Response code.

We can’t disable the plugin, but there must be something we can do in our team to configure the FR WebAgent to handle this issue.

Anyone who has done something similar can please guide us to resolve our issue? We also raised a Support Ticket, but we haven’t yet got any valuable response to solve the problem.
