Nicolas Richeton commented on HTTPCLIENT-1375:
----------------------------------------------
We found an alternate way to solve our use case without requiring change in
HttpClient (using a response wrapper which checks if the response has already
been sent. response sent = calls are made from an asynchronous validator)
While I still think this change may be useful in some other use cases, we no
longer need it right now.
If you don't see a valid use case, and no one request it, feel free to close
this issue.

> Add context attribute when request are processed by an AsynchronousValidator
> -----------------------------------------------------------------------------
>
> Key: HTTPCLIENT-1375
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1375
> Project: HttpComponents HttpClient
> Issue Type: Improvement
> Components: HttpCache
> Affects Versions: 4.2.5, 4.3 Beta2
> Reporter: Nicolas Richeton
> Priority: Minor
> Fix For: 4.3 Beta3
>
>
> With the current code, it seems to be no way to know if a request is being
> processed as a normal request, or if it is being processed by an
> AsynchronousValidator.
> Our use case is :
> - CachingHttpClient is used in a web app.
> - We use a custom cookie store to store cookies in user session (other
> usecases could be access to session/response objects while processing the
> request, custom code between CachingHttpClient and HttpClient).
> - We use background revalidation.
> - If the backend returns a cookie during revalidation, we have no longer
> access to the session so we want to ignore the cookie and prevent calls on
> session object.
> But we cannot identify the asynchronous request since it is the same as a
> synchronous one.
> A possible solution could be to add an attribute to the request context in
> AsynchronousValidationRequest constructor, something like :
> context.setAttribute( "asyncRequest", "true");
