Weaken outgoing ETags #45
Labels
Comments
Hello @dougwilson, I noticed that strong ETags (generated by Express) are the same for compressed and uncompressed responses. Is it somehow possible to generate a different strong ETag when the response is compressed? My use-case: we have an Express application => nginx => Akamai
Thank you |

When the response is compressed, alter any ETag response header to make it a weak ETag.
This is the easiest solution to deal with ETags. It's also what nginx did semi-recently to solve this (before their patch, they always dropped the ETag header completely) in http://trac.nginx.org/nginx/changeset/e491b26fa5a1908eb22dd96d19b4d26e25eeca2c/nginx
