Issue/Introduction

When trying to logout via "/affwebservices/CASSO/oidc/###/logout" endpoint, it returns HTTP 404 Not Found.

Cause

In the httpd.conf, there a line as below,

AliasMatch /*/logout "#:/###/CA/secure-proxy/proxy-engine/examples/siteminderagent/forms_en-US/msrlogout.fcc"

As the AliasMatch finds the match, Apache Web Server did not forward the request to the mod_jk/Tomcat.

Instead, it handled it by itself and tried to load the fcc file which is NOT hosted by apache web server so returns HTTP 404.

Resolution

In order to access the "/affwebservices/CASSO/oidc/###/logout", the "AliasMatch /*/logout" needs to be commented out or removed.
