[Resteasy-users] CacheControlInterceptor - is it overwriting cacheControl values for any @Cache annotated class/method?

[Gervasio A. <ger...@gl...>]

Hello all,

I have some concerns about CacheControlInterceptor:

1. I was debugging and I found CacheControlInterceptor has only one
CacheControl instance, with the values of the last initCacheControl method
call, which means, if I have, for example, two classes @Cache annotated,
with different values, CacheControlInterceptor on postProcess, will always
return the same values for all requests.

In code, this is the mentioned example:

@Path("/foo")
@Cache(*maxAge = 3600, sMaxAge = 3600*, mustRevalidate = false,
proxyRevalidate = true, isPrivate = false, noTransform = true)
public class Resource1 {

  @GET
  public String getFoo() {
    ...
  }
}

@Path("/bar")
@Cache(*maxAge = 500, sMaxAge = 500*, mustRevalidate = false,
proxyRevalidate = true, isPrivate = false, noTransform = true)
public class Resource2 {

  @GET
  public String getBar() {
    ...
  }
}

*Assuming Resource2 is parsed first for CacheControlInterceptor *, when
reaching GET <host>/foo I get in the response headers:
Cache-Control → no-transform, proxy-revalidate, s-maxage=3600, max-age=3600

And when reaching GET <host>/bar I also get in the response headers:
Cache-Control → no-transform, proxy-revalidate, s-maxage=3600, max-age=3600
while expected: s-maxage=500, max-age=500



2. Why 304 responses are not being included in postProcess method? They are
also good ones when using ETag checks.
What should be the best way to enhance CacheControlInterceptor to also
include those 304 on postProcess? Just implementing a PostProcessInterceptor
and registring it as @Provider?


Thanks in advance for your help.
