[Owncloud] Question about session timeout

[FOSS]

Hi all,
I stumbled about a small issue in my 'Shorty' app, maybe someone has 
got an
idea about this...

Shorty contains a 'Shortlet', a JS based bookmark that calls the app 
when
clicked within the browsers bookmarks. In the end this boils down to 
calling
the ownCloud app from a stored url directly pointing to the app
(https://...?app=shorty).

All usually works fine, with one exception:
when ownCloud has NOT been active in the browser before during "the 
current
desktop session" the request is always forwarded to the default app 
(files
app). "current desktop session" means: the users authentication is 
still valid
(cause stored), but the browser has been closed between now and the 
last
access of ownCloud.
When tried a second time, all works as expected: the shorty app is 
loaded and
the Shortlet serves what is is meant to do.

This leads me to the idea that there must be some kind of session 
timeout. The
session getting refreshed on-the-fly without forcing a relogin. But 
apparently
this refresh leads to a redirection to the default app...

Does this ring a bell somewhere ?
Anyone got an idea what is the cause of this annoying issue ?

Thanks,
Christian
