I ask there but I do not receive anything.
I will ask again here if anyone knows:
I´m using dsdelegator-service, it changes one datasource for other.
My problem is that it changes it for all applications and web sessions. What
I need is to change the datasource just for a single session. For example,
if user A logs in the application it should be delegated to datasourceA, if
user B logs it should be delegated to datasourceB, etc... And everyone
logged should work with his correspondent datasource...
Is this possible with dsdelegator?
Regards,
Hernán.
PS: Alexey, thanks for your patience! :)
