Graylog2-server: Search Query Flashes Login Prompt Briefly

[eroji]

After upgrading to Graylog 2.1.0, all search queries flashes the login prompt briefly as it reloads the screen with the results.

We are using Graylog on an input server and a web frontend server set as slave and serving only the web interface using Apache proxy to HTTPS. I verified that even with no Apache proxy, the behavior is the same.

Steps to Reproduce (for bugs)

Click on the magnifying glass or type in parameter to perform the search

Your Environment

• Graylog Version: 2.1.0
• Elasticsearch Version: 2.0.5
• MongoDB Version: 3.2
• Operating System: CentOS 6.7
• Browser version: Chrome 52 / IE 11.0

I was getting this issue before 2.1, though I think it may be more prominent in 2.1. At first I put it down to latency since I was trying to hit my Graylog cluster on east coast USA from Australia, but now I get it when running as local docker environment too.

I have not seen this issue in 2.0.x but I upgraded to 2.1.0 and getting this issue.

The flashing is somehow intended when you do a full reload of the page (or there is a redirection that triggers it, like the form that is submitted when searching). Anyway, I think we can mitigate at least part of the annoyance of that flashing:

• Remove the unnecessary redirections or submits we do in the web interface (#2488)
• Change the page we display while validating the user's credentials (responsible of this flashing), so it doesn't look exactly like the login form

I think the second change is small enough that we can put it in a patch release, and it can already avoid some confusion around this.

This has been fixed in #2802
