Oleg Kalnichevski commented on HTTPCLIENT-2406:
-----------------------------------------------
[~akasham1992] The original contributor of the `MemcachedHttpCacheStorage` has
long left the project but I presume that behavior was intentional as it aligns
with the behavior of other cache storage implementations. So, I do not think
this is a bug.
You are welcome to make this behavior configurable, though, by contributing
proposed changes as a GitHub pull request.

> Issue Type: Bug
> Components: HttpCache, HttpClient (classic)
> Reporter: Akash
> Priority: Major
>
> MemcachedHttpCacheStorage today calls remote cache store with "0" TTL
> indicating the remote cache to never clean up the cached data. Hence the
> remote cache memory is filling up over a period of time without any sort of
> clean up since the TTL is 0.

> try {
> client.set(storageKey, 0, storageObject);
> } catch (final CancellationException ex) {
> throw new MemcachedOperationCancellationException(ex);
> }
> } {code}
> From what I can tell, this is implemented this way for a long time now, is
> this intentional ? if not, do you consider it as a bug?
> Shouldn't the TTL sent as part of the response be used during this call?
