#2794 fixed specify connection attributes using the connection string Antoine Martin Antoine Martin
Description

Similar to #1160 / #2424, should re-use the same syntax, ie:

xpra attach tcp://127.0.0.1:10000/,cork=0,nodelay=1,encryption=AES:keyfile=key.txt,auth=file:filename=password.txt
#2793 fixed dangerous HTML5 client example Antoine Martin Kyler Laird
Description

On the HTML5 client page (https://xpra.org/trac/wiki/Clients/HTML5) there's an example of starting an xpra server with AES and password access. A URL is generated for a Web browser to access the server. One might conclude from this example that the password and AES key are required by the server. They're not. They're completely ignored on the browser's connection. The server has just provided world-accessible (0.0.0.0), unencrypted, and unauthenticated access to an xterm.

This is clearly demonstrated using the command line xpra client with the server as started from the example. Note that I do not provide the AES key, user, or password on either attempt to connect.

$ xpra attach tcp://localhost:10000 || echo -e "\n\nTCP connection failed.\nTry again with Websocket."; xpra attach ws://localhost:10000

Geometry appears to be on similar location, which would mean that the window should be there
