I have this codes in
<authentication mode="Forms">
<forms loginUrl="/Login" timeout="180" name="__Auth" slidingExpiration="true" />
</authentication>
And Plesk panel Session settings are as below : Authentication mode : Forms Sesion Timeout(minutes) : 180 And this settings automatically adding a line to web.config aas below:
<sessionState timeout="180" />
Everything seems good. But session ends too early (about 10 min) I could not find reason.
