How to disable Etag in Play 2.3 and change the cache-control , its using default in production mode

[Krishan Tyagi]

Hi Team,

Greeting for the Day!

I am new to this group and as to play framework. I need to fix the issue related to Etag in play framework, which is automatically generated by  play.( https://www.playframework.com/documentation/2.3.x/Assets#etag-support)

Here are the my questions: 

1. I want to disable  Etag generation by play. I had tried http.useETag=false , but does not works for me. 

2. I tried to change the max-age for cache, still it using the default 3600, how can I change it.

3. How can I override the assets controller code using java, where I can find out the assets controller code.

Please help.

Thank you i advance.

Hi Krishan,

1. There is not a configuration for that in Play 2.3. But you can strip the headers using a Filter (see docs here).

2. How did you change that? There are some docs here about how to configure it. Also, there is `assets.defaultCache` and `assets.aggressiveCache`. For both, the configuration format is the expected value for the header (for example `public, max-age=3600`).

3. Why do you need to do that? Assets controller solves a lot of problems to you. Anyway, the code is here: https://github.com/playframework/playframework/blob/2.3.x/framework/src/play/src/main/scala/play/api/controllers/Assets.scala

Best.
