Jenkins Proxy Loading page sends 2 XHR instead of one while waiting for jenkins to get unidled

[sthaha]

Steps to reproduce

1. Wait for jenkins to be idled
2. goto https:jenkins.openshift.io
3. Watch network requests to proxy

Expected:

• must see only one request to check if jenkins is up and running

Actual

• You would find two request being sent to proxy

Probable cause & solution:

index.html makes two calls - check() and then setTimeout. you would find that check already does a setTimeout so deleting the setTimeout after check may solve this
