Hi Tiran,
unfortunately in Grizzly 2.3.x FilterChain modification at runtime is
tricky (it's fixed on 3.0 branch).
We suggest to install all the Filters in advance and use a switch to
turn the filter logic on and off, like here:
https://github.com/AsyncHttpClient/async-http-client/blob/1.9.x/src/main/java/com/ning/http/client/providers/grizzly/GrizzlyAsyncHttpProvider.java#L2446
Specifically in your case the problem could be related to
FilterChainBuilder instance, which underneath updates existing
FilterChain instead of creating a new FilterChain instance.
You can try to create a separate FilterChainBuilder and initiate it with
all the Filters you need.
IMO FilterChainBuilder logic (updating an existing FilterChain) is wrong
and it has to be fixed. It has to create new FilterChain instance every
time build() is invoked. Will appreciate if you can bug an issue for this.
Thank you.
WBR,
Alexey.
