Hi Frederick,
I'm having this same issue, while using the text/xml header works I would like to know how to add support for other content-type headers used with feeds?
There are cases where we generate feeds for use in iOS apps and they have to have a specific content-type header in order to work.
I'm struggling to work out where in the code the content-type of text/html or text/xml is used to trigger the page cache, can you point me in the right direction? Would be useful if I could filter it perhaps in a later version.
Thanks!
