Hello,
I want to use xpra to serve an application from a server to some clients, but
everyone has to see a newly started up version of the application. The
application is a special calculator for material properties, and to prevent
updates on every single system, using Xpra to show the application in a browser
can be a perfect solution.
However, if I try to login with a second browser, the first login exits..
To allow multiple clients to connect to *the same* session, use the
`sharing` option.
When sharing is not enabled, new clients steal the session from the
current one which is disconnected.
I need multiple instances, if possible spawned right after connecting >
Are there some settings/configuration I can do the realize this?
Yes, many.
Which one is right for you depends on a number of things.
OTOH: user density, hardware available, security concerns, reliability
desired, type of application, etc.
If you can manage ports and / or user accounts and give each user a
different URL to connect to, then you can simply spawn new instances as
needed. (or even have a pool of sessions pre-launched, ready to be used)
If you want to use the same URL for all the clients, things are a bit
more difficult, but not impossible.
You could use some sort of apache or nginx proxy that does the
allocation. Or you could use xpra's builtin proxy server to spawn new
sessions on demand by configuring it with the `allow` authentication and
a matching "start-new-session" URL request.
The type of application matters: some applications don't mind running
multiple instances under the same user account, others won't work
properly, some will just refuse to run that way...
Cheers,
Antoine
Thanks in a advance,
Stefaan.
