HTTP code 302 encountered when deploying a web app on Google App Engine










0















I have a Java Servlet web application deployed to Google App Engine.



It has a login page and when the user is successfully logged in, it navigates to the Home servlet.



The http site stopped working from today's redeployment/upgrade to the app due to the code 302. And it only occurred on the computer when the redeployment/upgrade was performed.



When trying the app with the http protocol, it threw http 302 on the Home servlet. Then it navigated back the login page.



enter image description here



When trying with https protocol, however, it navigated correctly to the Home servlet on http 200.



enter image description here



Not sure if this is a GAE setting issue or a browser thing (I am with firefox)?



EDIT: I realised that the http site worked fine again if I cleared the cache on firefox. But when I accessed the https site, http stopped working again due to the same 302 issue.

          302s are not necessarily "failures"; They are redirects. When a user goes to log in, are you redirecting them? Perhaps from an http to an https login page? And when they log in, are you redirecting them back to the original page?
