Attila Kanto commented on KNOX-911:
-----------------------------------
Unfortunately the sticky session does not apply here, since Knox instances are
listening on different URLs, therefore the Knox instances can be differentiated
by URL, e.g. everything that is /gateway1/topology goes to Knox 1, everything
else which has a context path like /gateway2/topology goes to Knox 2.
What I would like to accomplish is to provide single point of access to
multiple clusters, which basically works the only issue is that Cookies are not
scoped to /gateway1/topology, therefore if I go to /gateway2/topology then
cookies are overwritten.
> Ability to scope cookies to a given Path

> URL: https://issues.apache.org/jira/browse/KNOX-911
> Project: Apache Knox
> Issue Type: Wish
> Reporter: Attila Kanto
>
> If there are multiple individual Knox instances behind of a reverse proxy,
> then it would be very useful if the Cookies could be scoped to a given Path.
> If a reverse proxy is put at the font of multiple Knox instances then scoping
> the Cookies to domain is not sufficient since the /gateway1/... and
> /gateway2/... cookies will overwrite each other.

> Proposal:
> Cookies can be scoped with Set-Cookie: Path=/somepath header field.
> It would be very convenient if this scope path could be set in
> gateway-site.xml and Knox would return it in Set-Cookie header field to
> clients.
