No Updates after Switching View Many Times
A single-page web application was getting push updates via SSE. Each view used a different SSE resource from the same endpoint. After a certain amount of navigations via the main menu, no updates would be displayed anymore.
This problem seemingly did not occur reliantly at first but as it turned out it would occur exactly after the seventh view changes (navigating 7 times via the menu). Every time a view is opened, its controller requests the respective SSE resource to get updates for the view. I was able to confirm this behavior on the API proxy which logged every request URL. But for any view change after the sixth view change, no request URL was logged which could only mean that there actually was no request coming in, despite the web application logging that it was requesting said SSE resource. Next I tried to replicate this behavior without the web application by just requesting the same SSE resource via Chrome multiple times. As it turned out, the seventh request never made it to the API proxy until I closed another open tab to the SSE resource. The reason was that Chrome only allowed 6 concurrent requests to the same endpoint and the actual web application never closed the connection for a SSE resource. Closing the connection when changing the view solved the problem.

Block undesirable websites and pop-ups on Google Chrome
While surfing on some sites, you can be overwhelmed with pop-up pages of advertisement and publicity and some of them can sometimes hurt a user’s feelings, children using their laptops for example or just people not wanting to receive those advertisements. In order to get rid of those pop-up pages and publicity, you can install an add-block extension by going to the Chrome Web store, extensions, and typing block websites on the research field. You can then choose the blocker that suits you the most and add it to Chrome. The most used one is still AdBlock and work efficiently.
The solution to this problem is:
1.Open chrome in your computer
2.In the top right click more
3. Click on settings
4.At the bottom, click advance settings
5.In the "Privacy and security" section, click on Content settings.
6.Click on Pop-up windows.
7. Disable the Allowed option.
