comment Is it possible to move MySQL to different hosting using replication?
--single-transaction is safe to use even in the presence of MyISAM. It will transparently downgrade to --lock-tables as needed, and do --single-transaction for the InnoDB ones. Though, honestly, if you're running MyISAM, you should take this opportunity to switch to InnoDB, anyway. One caveat with all of this: note that the mysql database has some funny bits in it, in particular things like permissions. Be careful that you don't lock yourself out in the course of importing the old host's data! You may also have some trouble if you're switching versions (e.g. 5.0 to 5.6).

comment Varnish as a cache proxy on openshift-online : openshift limits number of requests from same IP?
Sure, okay, that could happen if you have a cached copy eligible to be served to your loopback connection, whereas your browser was unable to hit the backend. That would require you to have configured backend health checking in your Varnish VCL, though; by default, Varnish doesn't monitor backend health. If you can get it to happen again, varnishlog output would tell you exact how and why Varnish is routing (or not) the request. You can also check the "Age" header you are receiving, or add a cachebreaker (e.g. ?abc123) to the URL, to make sure you aren't getting a cached response.
