HTTP/2 is the second main model of the HTTP protocol launched in 2015.
Round 46.5% of internet sites assist HTTP/2.
It has many options, comparable to:
- Compression of HTTP headers
- Push Applied sciences
- Load web page parts in parallel over a single TCP connection
- Binary protocol
- Decreased latency
Demo from AKAMAI exhibits that HTTP/2 is approx twice quicker than HTTP/1.1.
Do you know that LiteSpeed was one of many first net servers to assist HTTP/2?
In case you are utilizing a CDN comparable to Cloudflare, Incapsula, or MaxCDN, chances are you’ll not must allow HTTP/2 in your net servers, as you are able to do this from the sting of the CDN community.
Nevertheless, if that you must implement HTTP/2 in your net servers comparable to Apache, Nginx or IIS, learn on to learn to do it.
Comment: All main browsers (Chrome, Edge, Firefox, Safari, Opera) should use TLS 1.2 or newer for HTTP2 implementation.
However don’t fret for those who do some experiments. You will get the TLS certificates for FREE.
Implement HTTP/2 in Apache HTTP
HTTP/2 may be applied in Apache HTTP 2.4.17 or later model utilizing mod_http2 module. So when you have a model 2.2 or decrease, that you must improve to the suitable model first.
Let’s compile Apache HTTP with the mod_http2, mod_ssl module.
- Obtain the most recent model (I am doing 2.4.25 on Linux)
- In case you have downloaded the .gz file, extract the downloaded file
gunzip -c httpd-2.4.25.tar.gz | tar xvf -
- You will notice a brand new folder being created. Go in there
- Construct the Apache from supply with the configure command
Comment: For those who do that on a model new server, chances are you’ll run into an error putting in dependencies, and this information ought to make it easier to with that.
./configure --enable-ssl --enable-so --enable-http2
- Be certain that there isn’t a error within the above command. As soon as executed, run the next make command
make make set up
This concludes that Apache HTTP has been put in with the HTTP/2 module and it’s time to do the required configuration.
- Again up the httpd.conf file (default location /and many others/httpd/conf/httpd.conf)
- Open the httpd.conf file with vi and ensure the next exists; if not, add it.
LoadModule http2_module modules/mod_http2.so
- You then want the Protocols guideline as under
Protocols h2 h2c http/1.1
For those who allow HTTP/2 for a person digital host, it’s essential to add Protocols underneath the respective VIrtualHost.
Comment: There are three parameters within the above Protocols guideline
- h2 – Instruct Apache to assist the HTTP/2 protocol over SSL/TLS
- h2c – Instruct Apache to assist HTTP/2 over TCP
- http/1.1 – if a shopper doesn’t settle for HTTP/2, then make the request over HTTP/1.1
Restart the Apache HTTP server reload the configuration.
Now Apache HTTP occasion is enabled to assist the HTTP/2 protocol.
Implement HTTP/2 in Nginx
Nginx 1.9.5 or a better model helps HTTP/2, so first be sure you have the suitable model put in.
Enabling HTTP/2 in Nginx is only a matter of including the http2 parameter within the pay attention instruction.
- Again up the nginx.conf file as common (default location /and many others/nginx/nginx.conf)
- Modify with vi and add http2 under pay attention guideline
server {
pay attention 443 http2 ssl chandan.io;
…....
}
As I discussed above, HTTP/2 is supported solely over HTTPSso that you must add underneath server block with SSL configuration.
In case your SSL configuration is in one other nginx.conf file, that you must replace it there.
As soon as executed, restart the Nginx to make the configuration energetic.
Examine if the web site helps HTTP/2
There are a number of methods to test whether or not the web site helps HTTP/2 or not.
Manually – open IE/Chrome/Firefox and press F12 >> go to Community tab and you need to see Protocol as HTTP/2.
On-line – you should use the HTTP/2 check instrument.
That is all for right this moment. I hope the above lets you allow the HTTP/2 protocol in Apache and Nginx net servers for quick loading net pages.
