* Hi,
* I’ve been a CloudFlare user for a long time so I guess you know I like it. I’ve
always managed the account from the web interface. I decided to get the plugin
as it has a feature for HTTP2 Server Push. I don’t see any other way to enable
this feature via the CloudFlare website.
* I thought there would be some panel where I could decide which files to push.
Instead, it looks like the same 5 files. How are these selected? I was thinking
maybe you had some magic for determining what assets were needed “above the fold”.
* The reason I ask is it doesn’t make sense to me to push print.css.
* I think I may have seen something in a previous post about a 4k limit. And I’m
guessing that would include all my security headers and content security stuff
which is lengthy.
* The other thing I noticed is the plugin seemed to have disabled RocketLoader.
I’ve turned it back on from the web. Is there any incompatibility?
* Thanks in advance.

* Hi,
* A web page is loaded over HTTP2 if it contains the [``](https://w3c.github.io/preload/)
tags necessary for HTTP2, for example:
* ``
* The setting in the WordPress plugin automatically generates these `` tags
for you. If you don’t want `print.css` included you can manually generate your
own `` tags.
* The 4kb limit is due to some fast-cgi implementations, Cloudflare has an 8kb
limit. If you aren’t running fast-cgi then your limit is 8kb.
* Rocket Loader is disabled if you enable “Apply Default Settings”. This is because
certain cache configurations on WordPress can break with Rocket Loader enabled.
* Thanks,
John

* Thanks John.
* I appreciate the fast reply.
* Glad to know Rocket Loader can work with the plugin in my case. I don’t recall
having an issue before. I just have to remember to use “Disable cache” on Chrome
Dev tools so I can see the “push”
* This whole performance area can get so crazy when you have multiple plugins that
may overlap etc (SiteGround’s caching plugin, WP Rocket, CloudFlare). And I also
have to recognize that you need to design for us “masses”.
* It sounds like…I’ll have to manually create my then. I’m not sure I would
get enough gain.
* If you need feature requests, it would be great if you allowed end-users to submit
files via some interface. Maybe like the way WP Rocket allows me to put in entries
for DNS pre-fetch.
* In the meantime, I need to see if my host uses fast-cgi. My header is around
3.3k so maybe there’s a way to get another file or two.
* Thanks for the clarification
