Sorry this I count as basic knowledge/settings. This thread explains it very well:

HowTo: Nokia N900 HTTP Proxy Setup Tutorial

My post belongs to the at the moment solo discussion started in post 44 in this thread, but all others are welcome to join. There you will also find nginx which you will need.

But I still try several things what is now working http to https bump and there I need to try different pages, so it was working for the example page which has strong limitations to connect to it but to show the http content there is no challenge. So it is still not clear how hard-coded urls for scripts/images behaves

But I would like to have https(tlsv1.0) bump to higher tls versions and this seems not so easy to set up. Normaly the first one is enough but for paranoid person who are not sure if something on the device is listening would this maybe a little better but it is no guarantee...
