 I will move this one to the "post 2.0" wikipage, it is not a bug under the
 current specification for varnish.

 If at some point we implement support for this, I don't see it as a "101"
 level feature.

 Getting all the bits and pieces of an ESI page compressed so that they can
 be concatenated as a compressed object is not a trivial undertaking, and
 not getting it right means that you spend a lot of cpu time compressing
 objects that only one client will see.

 In particular I have a hard time seeing the benefit from compressing the
 page on the backend, uncompressing it on varnish, doing ESI, and then
 compressing the result for the client.
