Hi all,
We have a feature to implement and are wondering if header-rewrite is the
right home for this feature. In a nutshell, when using ATS as a reverse
proxy, we want to redirect all http requests with a certain cookie to their
https counterparts but not using remap.config. The remap.config constraint
comes about because we already have a ton of existing rules and creating a
blanket rule is not feasible. We could either create a simple plugin to do
this or enhance one of the existing ones with header-rewrite being the
leading candidate.
But I feel this may not be right because the way it is implemented and
designed, header-rewrite only changes the headers and always continues the
transaction. To do the redirect outside a remap context, it would have to
error the transaction. So now it's also changing the control flow of the
transaction. And just adding a feature to our requirement ("switching" the
scheme) may not be very reusable/generic to others. A generic feature where
you could construct the redirect location using various components
(scheme/domain/path/query etc.) of the incoming URL is a fairly complex
feature.
On the flip side, creating a plugin just to switch schemes creates extra
deployment and maintenance overhead.
Any feedback would be much appreciated, thanks.
