#1103: squid doesn't like POST generated by the 'join' button in groups

Description of the bug

I use Epiphany/WebKit behind a squid proxy. When I click 'join' in a group, I get this error:

ERROR

The requested URL could not be retrieved

Invalid Request error was encountered while trying to process the request:
