Hi,
Using Phoenix, how do I direct HTTP clients through an alternative pipeline when a certain HTTP request header is present?
I’m guessing a plug could this but pipelines contain plugs so that’s too late in the process. Seems simple enough though, but I can’t find where to start 
tia!

I’m not sure if there’s a way to assign pipelines in a phoenix router other than by path, but you could put your plug into the endpoint.ex and redirect to different routers.
Edit: another option might be a plug, which does only apply another plug supplied in the options on demand.

You can put plugs in Controllers too. You can make plugs that run ‘other’ plug lines (it is just simple init/call stuff) depending on various things. Etc… Lot’s of styles, the one I’d pick depends on precisely what is needed to be done.
