java.net.SocketTimeoutException When switching from https to http

I use the following Java code to test a redirect from http to https and the other way round.

Setup1:
My server redirects http requests to https.

The is works fine with the code above.

Setup2:
My server redirects https to http.

This leads to the following error:

```

When I reset my simulator with `Reset Content and Settings..` from the menu then setup2 works without problems. When I switch to Setup1 it also works but when I switch to Setup2 I get the same error again.

It seems to me that there is some kind of connection caching going on here. Is there any way to reset this without reseting the device?
