Please wait with merging. There is still an issue. I'll come back to you.

I fixed it. I missunderstood some python specifics. Since micropython does not support method inspection and I wanted to make sure your WebServer stays compatible, I had to introduce HTTP Method specific registration methods.

• onGetPath (same as onPath)
• onPostPath
• onPutPath
