Whenever we signout from AEM publish instance ,it will redirect us to the default page i.e geomatrixx
localhost:4503/content/geometrixx/en/products.html
/core
/config.author
com.day.cq.commons.servlets.RootMappingServlet
change the property rootmapping.target to the desired page you want to redirect after logging out from publish instance.
localhost:4503/content/geometrixx/en/products.html
So to override this we need to map the own URL to the confugiration which override the default one.
Goto
/libs
/cq
/core
/config.author
copy the node com.day.cq.commons.servlets.RootMappingServlet into apps as the sequence provided above
ex: /apps
/cq/core
/config.author
com.day.cq.commons.servlets.RootMappingServlet
change the property rootmapping.target to the desired page you want to redirect after logging out from publish instance.
