Summary

0031077: There are some problems with offline mode when the server is overloaded

Description

When the server is overloaded, the Web POS should automatically do login in offline mode, or switch to offline mode on the fly if the user is already logged in and doing operations.

However, this doesn't happen correctly. There are two main reasons for this:
- The timeout of a request to the backend is too big, which can confuse the user when reloading the page.
- Several requests to the login.Context servlet do not have timeout, which can block the Web POS in the case the server is still alive but very overloaded.

Steps To Reproduce

- Run a report or a task in the server which makes it run out of memory, thus making it unable to respond properly to the requests.
- Try to login in the Web POS. Verify that it's not possible to do it.
