As I'm the author of RESTForms, I'd recommend that. The advantage is that it offers not only JSON<->object transformation, but a complete CRUD REST API for your data.

Calling @Stefan Cronje

All approaches you are considering can work. if you're storing everything in one database, I'd recommend RLS.

Much more important question is do you need storing everything separately or in the same place.

Advantages of separated databases/servers:

• Easy to scale
• Would work faster on a lot of cases
• Easy to delete/rebuild a chunk
• Easier security

Advantages of unified database/server:

• Cross-chunk queries are easier (For example: This venue is sold out on the dates you need. We recommend the following nearby venues)
• Simple Backup/HA strategies

You can just pass the stream directly, no need to read from it:

set parObj = {}.%FromJSON(%request.Content)

Some XSLT engines can process arbitrary javascript as code.

Achieving  FIFO with Ensemble is an interesting task.

Do you control queue population?

If so  you can send the message only if the queue is empty and process is idle.

For example create a proxy process that sends only one message at a time.

Set when? Set how often?

Check your BO message map. There's no entry for Test.SubscriberX class there.

Why is it going to intersystems-community on F5?

To check for updates.

What browser is that?

Try Google Chrome.

InterSystems Caché supports passwords with Unicode characters for basic authentication starting 2018.1.

Earlier versions should require ascii-compliant passwords.

You can use PasswordValidationRoutine to enforce that.

Please ask this as a separate question.

Are there any errors in browser console?

Just installed  Webterminal 4.8 on Cache for UNIX (SUSE Linux Enterprise Server for x86-64) 2015.2.1 (Build 705U) Mon Aug 31 2015 16:58:02 EDT [HealthShare Modules:Core:14.01.7952 + Linkage Engine:14.0.7952] and it seems to work.

Do you see /terminal web app in SMP? If it's not a production system try to give %ALL role to check if it helps.

The link should be:

http://host:port/terminal/

Right.

@Alexey Maslov does exactly that at the beginning of his code sample:

new $namespace
set $namespace="%SYS"

Here's it in class doc. You can only see it in class explorer for %SYS namespace.

It's available in 2017.2 in %SYS namespace.

Any reason you want to do that?
