Re: Intermitent 404 and 403 on proxied site while enabling Websocket

[Frank Gingras <thumbs@xxxxxxxxxx>]

Davi,

2.4.4 does not support WSS, so this isn't likely to work at all. If that is a distro package with backports, it must be an ancient EOL version, as I'm not aware of any distro still shipping 2.4.4.

It would also be useful to see the output from apachectl -M

Hi team,

We are using httpd 2.4.4. This server has proxy reverse configured to more than 70 sites. While we enable a new proxy to a websocket site, other sites where running fine start getting intermittent erros 403 and 404. Imediatley, if we remove the new site and reload configuration, everything start working normally aging. The proxied websocket site always run fine.

We've tried different RewriteRule without any positive effect.

Do you have any advise? Any known issue regarding multiple virtual hosts and websockets?

Thanks,

Davi
