Subject: store filters on server
X-Git-Url: http://git.rot13.org/?a=commitdiff_plain;h=ae6feddd161a9bf80edcad62e12899c3d8f06514;p=MojoFacets.git

store filters on server

This allows us to have huge faceted filters.

We stored filters in cookie and that works until whole session
(including all filtered values) is smaller than 4K which is
limit of cookie size (session in stored in cookie)
