Hi Andrew
Given that the two above caching plugins seem to extremely popular (approx 9 million downloads between them) and would appear to be `best in class' for something which is rather important for site performance and SEO, this is a bit of a drawback.
Do you think you will get resolution on this issue ? If not, are there other Wordpress caching plugins which do not cause conflicts with your service
FYI, I'm using Wordfence Security which is extremely popular & very highly rated. The latest version includes a caching utility called Falcon Engine which claims to offer the fastest WP caching available. I guess it's too early for you to definitively state whether it causes conflict with your service so will you be running tests to gauge it's suitability as an alternarive caching plugin ?
Here's the link if it helps:
