How do I turn off ETag(s) in Ruby on Rails v2.3.5
When I do a direct request to to the RoR/Mongrel an ETag header is present.
response.etag = nil in a before_filter does not work. The etag is generated just before the response is send (it's caluculated from the body so after all rendering has been done).
The proper workaround to disable etag use and generation (and so save the time spend in md5) it this monkey patch:
module ActionController class Request # never match any incomming etag def etag_matches?(etag) false end end class Response # fake rails that our response already has an etag set and so none is generated automatically def etag? true end end end
