RTMPS connection impossible through Squid proxy

Some of our customer, who uses a Squid proxy, cannot connect to our service using the RTMPS protocol because of a bad HTTP CONNECT request done by the Flashplayer :

This works : CONNECT server.com:443 HTTP/1.1/r/n

This doesn't (FP request) : CONNECT server.com:443 HTTP/1.1 /r/n (you can see a space (0x20) after HTTP/1.1)

This problem was already discussed in a previous thread : here, but this bug has not been fixed yet...

Do you know if it will be fixed one day (I can't believe it is that long to fix it) ?

Or at least has someone a solution to allow Squid to let this misformatted request work ?

Any help will be greatly appreciated
