RTC WebSocket browsers compatibility (RealThinClientSDK_v800_rc10)

[Ecole7]

Hello,

WSockServTest tested with ws.html does not work with Firefox browser (52:01). It seems impossible to switch to websocket mode.

The test on the site https://www.websocket.org/echo.html is OK with Firefox.

Everything else seems perfect. But compatibility with some browsers may be a tricky thing.

Thanks for reporting this.

It was the automatic recognition of Web Socket upgrade requests, which was expecting the exact word "Upgrade" to be in the "Connection" request header, but "Mozilla Firefox" was sending "keep-alive, Upgrade" instead, so the Request.WSUpgrade property wasn't automatically set to TRUE on the Server.

I am preparing the next update now (v8.00 rc11), which fixes this by ignoring anything else that might be in the "Connection" http request header as long as the word "Upgrade" is found and the "Upgrade" header is also present, with the word "websocket".

Best Regards,
Danijel Tkalcec
