Many Requests in access.log if php Sessions ended

Hello,

if PHP session ends the browser starts to make many Requests to the CRM Server.

If many users are using the CRM at the same time and everybody has about 2-3 tabs opened the Apache gets too many requests.

you can reproduce this if you delete all PHP Sessions in the server.

after that each Browser Tab reloads and the reload intervall is very short.

This nearly kills apache if many people are using the System at the same time.

any ideas how to disable this reloading?

reegards

we are using 7.5.1.

But in current versions this seems to be fixxed.

As this has been resolved in the latest version would this be suitable to state this issue as resolved?
