… I've hit “send” button by mistake…. Hi Gustaf I’ve noticed you had uploaded a simple client interface to websocket-procs.tcl. https://bitbucket.org/naviserver/websocket/src/master/websocket-procs.tcl <https://bitbucket.org/naviserver/websocket/src/master/websocket-procs.tcl>
However, I hit another error related to [dict], because the url doesn’t return a path, when [dict get $d path] runs. The websocket sample is "wss://javascript.info/article/websocket/demo/hello <wss://javascript.info/article/websocket/demo/hello>”,which returns the following content [12/Jul/2020:21:10:09][22414.7efbf37fe700][-conn:iurix:0:9-] Notice: D proto wss host javascript.info path article/websocket/demo tail hello I’m going to continue writing this client. I don’t know if you are in the middle the implementation but I shall thank you in advance. That’s been very helpful already.
