Requests for custom web app deployed in Tomcat get redirected to ThingWorx

Dear devs,

I am using a Thingworx Foundation Trial, and I tried to install an additional Web App located in the tomcat/current/webapps folder, along with the Thingworx.war. The thing for me is, when I try to access the paths of /myapp I get prompted with the window asking for Thingworx credentials, and when I enter those I am redirected to the Composer.

How can I solve this? I have seen that there are quite a lot of filters configured in the /Thingworx/WEB-INF folder, but I don't really want to disrupt anything.

Thanks!
