Hi there,
Whats the best way to be sure that memory is disposed in browser/tab closes?
My IIS crashes due to high memory usage.
Should these two parameters in web.config be enoutgh for the job?
<system.web>

sessionstate is not a Wisej option. It’s Asp.net. The session timeout in wisej is an option in default.json - refer to extensive online documentation.
If you have a memory leak in your code use the memory profiler to find out which root in your code is holding references.
You don’t need to change anything related to the GC. It’s all handled automatically by .NET. Wisej doesn’t have anything to do with memory management and there is nothing for you to change other than avoiding memory leaks.
Memory leaks in .NET occur when you have a root (see .NET documentation about roots and garbage collection) that holds on a reference. It’s all standard .NET stuff - it’s not and cannot be changed by wisej or any other framework.

hum ok,
but that config, will lead me to the wisej form with the session timeout, and i don’t want that to appear, i have two situations:
1,
– app has a login interface, and i don’t want users to be all the time extending the timeout
2,
– app has a dashboard that run’s by itself, i don’t want that form to appear ontop of the dashboard
is where a way for the wisej timeout take effect only when the browser closes or something like that?

That unrelated to your memory leak. There is a whole section in the docs explaining session management and exactly your situation.
