HTTP/2 Server Push

[Daryn]

Does vb5 allow for Server Push via http/2? Messing around right now with h2 and seeing a lot of mixed h2 and 1.1 requests. A little new to this protocol, so I'm wondering if I'm missing something.

As I don't know what you're talking about, I would say that this is something controlled by the server. Not a web app like vBulletin. vBulletin doesn't really handle any protocols, the web server handles requests and forwards them to vBulletin.

Looked it up. We do not support this at this time.

Good to know. Looks to me like adding the rel=preload to links is a part of it. Perhaps something to look into for a future version.

Thanks.

It would be tricky to add because it will cause issues for many customers and negate the performance benefits of caching resources on the client device.

If I understand right there isn't anything needed on our end besides SSL?

Here's an article by my host on the subject: https://www.siteground.com/blog/http2-supported/

Currently, we rely on browser caching on the device... So you'll download the CSS, Javascript, and Images which will be cached. The next page loads will not request these from the server as you've already has them. This speeds things up for the end user and reduces the server requirements and saves bandwidth.

What the original poster is asking for is that we can put the resources (CSS, Javascript, Images) in the request headers. So the browser automatically requests these resources before the page stops loading. Unfortunately, it doesn't take client-side caching into consideration. So there are more downloads per page. With vBulletin, we have a lot of CSS and Javascript involved. Since they will download every page load, it will slow down the rendering of the page on the client.

However, individual site owners can use .htacess to handle this if allowed by the server. See: https://httpd.apache.org/docs/2.4/en...p2.html#h2push
