ringserver configuration #28

Hi, I was exploring my options for displaying waveforms in real time in a web page, and I came across this: http://crotwell.github.io/seisplotjs/tutorial/tutorial7.html by @Crotwell . It is not clear to me if it is possible to configure my ringserver the same way, i.e. to accept web socket connections using the DataLink protocol. I installed the ringserver and it works as expected, creating the ring buffer, and it can be configured to run as a SeedLink server and everything. However I still haven't managed to make something like the aforementioned link work with my ringserver, so I wonder if it is possible at all, or if I am missing something obvious in my .conf file or firewall settings or something. Any hints that may help me?

Yes, that code was originally designed to work with ringserver.

The ringserver conf option I use looks something like:

ListenPort 6382
WebRoot /data/scsn/www/ringserver-web
HTTPHeader "Access-Control-Allow-Origin: *"

but you can also use just HttpPort I believe. The HTTPHeader is important to allow connections from pages servered by another web server.

This did the trick. I didn't realize that the WebRoot option was necessary. Thank you!

Hmm, I wouldn't think the WebRoot is necessary as ringserver will answer HTTP requests (if configured to do so) regardless if a WebRoot has been set. The HTTP Access-Control-Allow-Origin is definitely important though.
