Nice! I think we can improva a bit before committing.

Doesn't flow well perhaps Support for the next version of the HTTP protocol, HTTP/2, is included by default when installing the Apache port with pkg and is enabled by default if you build Apache from ports. |
| 3740–3741 ↗ | (On Diff #78406) | "packet header data is compressed and encryption is used by default." ? |
| 3743 ↗ | (On Diff #78406) | I don't believe that's true... All browsers still support http, but https is preferred. |
| 3761 ↗ | (On Diff #78406) | That's bad... Should change the port to default to mpm_event. |
| 3767–3774 ↗ | (On Diff #78406) | On second thought, this may be confusing to the reader. We can leave it out. |
| 3812 ↗ | (On Diff #78406) | Range 192.0.2.0/24 is reserved for documentation, see rfc5737 |
| 3822 ↗ | (On Diff #78406) | <para><acronym>HTTP</acronym>/2 is also available for reverse proxy connections. Enable the mod_proxy_http2 module and change the ProxyPass or RewriteRule [P] statements to h2://</para> |

Thanks, everyone, for the prompt feedback. I'll get a new version submitted soon but will also wait to know what changes will be updated to the port. Stay safe everyone!

| 3740–3741 ↗ | (On Diff #78406) | Hmm, this was my understanding that, as long as h2 is being used, it's default. When using h2c, or http1.1, none of this is true. Maybe I should make this more clear. |
| 3743 ↗ | (On Diff #78406) | Hmm, I guess this could be worded better as well. Firefox and Chrome, from my reading of the documentation, will only support h2 over HTTPS and fall back to HTTP1.1 otherwise. I'm glad you mentioned something here. |
| 3761 ↗ | (On Diff #78406) | Should I leave it in for now? I can wait, this doesn't have to land ASAP, just let me know please! |
| 3767–3774 ↗ | (On Diff #78406) | Okay, we can also change this from a warning to a note and/or reword this to sound less dire. The port can also be updated, but I do want to point it out in the text. |
| 3812 ↗ | (On Diff #78406) | Yes, I know, this was my bad. I copied and pasted directly from my test system and never updated the address range. I'm going to fix this before submitting an updated patch. :) |
| 3822 ↗ | (On Diff #78406) | Oh true, I forgot to add information on using mod_proxy_http2. I'll work something up in the next revision. Between that and updates to the port, I think we will have this all nailed down soon. All in all, great comments and feedback. I probably should have given you and apache@ a notice about the incompatibility with mpm_prefork. |

Good stuff! I'm going to check on the Apache defaults!

| 3743 ↗ | (On Diff #78406) | Correct on the HTTP/2 side, that requires SSL with browsers. h2c is rare, I have yet to seen it "in the wild". https://en.wikipedia.org/wiki/HTTP/2#Encryption |
| 3761 ↗ | (On Diff #78406) | Leave it in. We'll have to tread carefully. mpm_prefork seems to be default in the Linux world, we need to check Apache's default build config etc. |
| 3767–3774 ↗ | (On Diff #78406) | "A separate mod_http2 port exists, but you do not need it for HTTP/2 support. The separate port delivers bug- and security fixes earlier than the Apache bundled version." |

Update with feedback from brnrd. I think everything has
been addressed with this update. Thanks team!
Updating D26850: Add a section on enabling HTTP2 in Apache, included in this
diff is the following:
Document the second mod_http2 port and why it should be used;
Document how to enable for single virtual hosts or globally;
Note incompatibility with mpm;
Show how...
