Hi,
I was just wondering what the recommended way of caching is. Is there only ETag? Should one use ETag for caching?
As far as I can tell If-Modified-Since is not supported. Is there any plans of making the HTTP response include the last-change date so I can send requests with If-Modified-Since header?
Cheers, Reinhard

Actually ETag doesn't seem to work.
Request is setting If-None-Match correctly but server is responding with 200 OK + data instead of just rending back a 304 Not Modified: http://snag.gy/mIkt9.jpg

Have you taken a look at this thread: https://www.themoviedb.org/talk/5162e6e8760ee374b610b24e

(my bad, had If-Modified-Since set which apparently cancels out If-None-Match)

Got it working now. Just need to make sure If-Modified-Since is not set if If-None-Match is set. Though why the above curl call didn't work is beyond me...

If I get back "304 Not Modified" does the request count towards the rate limit?

Hi rednoah,
It will count towards the rate limit. The benefit is the saved transfer on both our end and your client(s). This results in less resources being used all round and just being a better API consumer.

I am trying to use etags but it does not seem to work for me.
Can anyone see what I am doing wrong?
So here we can see the etag is:
Now I pass that same etag in the If-None-Match header...
I still get a 200 response and the entity.
What have I missed?

I can replicate this, I suspect the change was caused when we removed Varnish from our stack. I'll have to spend some time digging into this and seeing if we can take care of this properly at the app level.
Here's the relevant ticket.
Cheers.

3.5 years later, still looks like etag isn't working:
curl -i -H Accept:application/json -H If-None-Match:df2617d2ab5d0c85ceff5098b8ab70c4 -X GET 'https://api.themoviedb.org/3/genre/movie/list?language=en-US&api_key=API_KEY'
I still get 200

That is correct, it hasn't been fixed yet. I do not have an ETA for this issue at this time.

By the way,
If-None-Match
works on most API calls now (the ones that return anETag
). I'll try to find some time to get the remaining methods that aren't returning anETag
completed soon.Responds with a regular
200
response, and if we make a call withIf-None-Match
...We're properly returning a
304
.Cheers.
