asp.net session timeout on lost connection

Question

I have an intranet page which needs to not time out (indefinitely) and I'm using JS to keep it alive that way.

But I am having one issue that happens when the user loses the connection (happens frequently due to to going in and out of wifi range) the session times out then.

How can I keep the session up/refresh it if that happens?

Answer 1

How about increase the session time out on web.config ?

<configuration>
  <system.web>
     <sessionState timeout="120"></sessionState>
  </system.web>
</configuration>

Other possible way is to make your database, connected with the user cookie, and use your "custom session" data that are totally connected with your users.

Answer 2

Try using in web config if you are using Form Authentication

<system.web>
    <authentication mode="Forms">
          <forms timeout="120"/>
    </authentication>

    <sessionState timeout="120"  />
</system.web>

Answer 3

first Sets the session timeout on the server is for all session Rather than a single Session

out wifi range is the entire network are broken so not keep alive

You have to use cookie use cookie keep alive
