Hello all,
I’m exploring the possibility of adding ETag headers to images my
Tapestry application is serving, to help improve performance on slower
networks.
It seems that Apache Server automatically adds ETag headers to images
sourced from static files (Tapestry @Asset), but not when Tapestry
dynamically generates an image from a database BLOB (and without file
extension, eg. .png).
Essentially, the app would need to return a “304 Not Modified” in
response to a conditional If-None-Match request from the client, if the
image hadn’t changed.
I couldn’t find anything about this in the Tapestry docs, and am
wondering how others might have implemented ETag headers within their
Tapestry applications.
Kind regards,
Chris.
