http-2 | Pure Ruby implementation of HTTP/2 protocol | HTTP library

You're using Gatling 2, that has been dead for year and whose last release was in March 2018. The WebSocket support was completely redesigned in Gatling 3, which was released 3 years ago. Please check the migration guides for the new WebSocket API.

As a web site option it is pretty much dead. As well as Chrome’s stated position (which has not changed but also not been actioned… yet) there is a new consideration which will likely kill it off first: HTTP/3.

HTTP/3 is already supported by 12% of websites and 20% of web traffic despite not even officially being signed off yet (though it’s as near as can be).

Chrome has not implemented push on HTTP/3 (and seem highlighlyunlikely to given their stated position to drop it for HTTP/2) and because of that neither has Cloudflare (one of the leading CDNs working on HTTP/3 and powering 10% of the internet). I’m not sure of other’s position on this but with those two out that’s a big chunk of support.

Some sites will always languish on HTTP/1.1 (without push), those that adopted HTTP/2 quickly and completely enough to use push willl likely move to HTTP/3 (especially if behind a CDN like Cloudflare) so there really is very little that’ll be left behind on HTTP/2 to be able to use push. So what little usage there is of HTTP/2 push (~1.25% of sites) will dwindle anyway until it’s a negligible amount (if it isn’t already!).

Push is dead for web browsing. Though more recently there has been a big push (pardon the pun!) by browsers and CDNs to support 103 Early Hints - a much safer, less risky option that can deliver many of the same benefits as push.

The problem is that the answer you link to, as well as the version of ruamel.yaml.jinja2 that you are using do not know about the jinja2's if-statement. During loading the {{ part of {{- is replaced so it can be recognised as YAML, but that causes parsing issues (because it isn't indented properly nor a key-value pair). Instead it should be turned into some form of comment, as is done in ruamel.yaml.jinja2 version 0.2.6.

With that you can load, update and dump this multidocument YAML file:

You were almost there - Your code is :

Move the call to curl_easy_getinfo(CURLINFO_RESPONSE_CODE) inside of your main loop. Use curl_multi_info_read() inside the loop to detect when each request is complete before retrieving its response code. For example:

Okay, I get it, I didn't know that TelegramBotApi runs a grizzly server underneath and that was the reason for my mistakes For those who ever come here with the same problem, I will describe the solution : Let's start with the fact that for the test on localhost we need a public address , e.g. ngrok , then we have to do the following, start grizzli on , let's say port 80 (localhost), specify the correct ngrok url , and then run spring boot application on , let's say port 8080, examples in the code

For ex. ngrok forwarding: Forwarding http://b44ecce72666.ngrok.io -> http://localhost:80 Forwarding https://b44ecce72666.ngrok.io -> http://localhost:80

An HTTP origin can advertise the availability of an equivalent HTTP/3 endpoint via the Alt-Svc HTTP response header field or the HTTP/2 ALTSVC frame (ALTSVC), using the "h3" ALPN token.

In this case, Alt-svc is present:

After enabled HTTP 2.0 in your webapp, you need clear cookies and sessions, then you will find your webapp is works fine with HTTP/2 . Or wait a little longer.

1. You can open a new inprivate window, it works for me.

2. The second question is that enabling HTTP 2.0 will not have a negative impact on your application.

3. The third point, there are also considerations about the correct version of .Net Framework, 4.6.2 and above all support HTTP 2.0.

I have tested that HTTP Version is supported in .NET Framework 4.6.2 and above. So your first question, you can open the privacy window and try again.
