Hi Conrad,
I will see if I can change to POST.
To explain a bit: Jalview (Java) application uses POST, we now have a Javascript version which for the moment is limited to sending GET requests, so I tweaked the code for that. I will see if I can persuade it to fake a POST instead and let you know what I find.
Thanks,
Mungo

Hi, Mungo.
I tried using the RESTserver on a recent daily build, and it opening
4zhp worked fine. Since RESTserver hasn't changed in a very long time,
I suspect the results would be the same with 1.13.
The way I tested it is to start the RESTserver in Chimera, and then go
to a browser to visit "http://localhost:PORT/static/cmdline.html" where
PORT is the port number reported in the Reply Log. A form is displayed
in the browser and I type in "open cifID:4zhp", which runs the command
and displays Chimera messages in the browser rather than the Reply Log.
I did notice that your tests show messages like:
> 127.0.0.1 - - [01/Feb/2019 10:32:03] "GET /run?command=list%20residues%20spec%20%230 HTTP/1.1" 200 -
whereas mine show:
> 127.0.0.1 - - [04/Feb/2019 12:02:46] "POST /run HTTP/1.1" 200 -
That looks to me like you are sending requests using http GET, whereas
my tests are using POST. It /shouldn't/ make any difference, but would
it be possible for you to test using POST to send requests to Chimera
instead of GET?
