Re: zero install query

Dear Bastian and team,

Could you please clarify if it is possible to use network path
(\\fileShare\folder\) for caching instead of local disk? If yes, kindly
point me to the document or could you explain how to configure it? If it is
not possible, is there any workaround or can I implement IFeedCache
interface to achieve this? And how to integrate the newly implemented cache
management with zero install.

Thank you in advance,
Sanketh
