The Web VS HTTP

The W3C website is a great resource, the section on ARIA](https://www.w3.org/WAI/ARIA/apg/) and as others have pointed out the patterns section is great and includes examples. Source: about 1 year ago

I copied that directly into the validator at w3.org and it showed no errors. https://validator.w3.org/nu is what you're using, yes? Source: about 1 year ago

Time to start Googling! Those are all solvable things that you can fix. The last ones in black are strange though... I have no idea what the reference to w3.org is for. Source: over 1 year ago

Google tells me some pages on my website have mobile usability errors - detailed results on GSC show 45 of 75 resources couldn't be loaded, many are apparently script and stylesheet issues to do with the theme and some plugins. The affected pages also load very slowly on GTMetrix. I turned on minify html, css and js on my caching plugin but it didn't seem to help. I did a Validate CSS check using a tool on w3.org...

Depending on what prompted this issue, there are a myriad of resolutions. If it's your SSL certificate then you simply need to get that registered and compliant. If it's because of bad coding then you can check out https://w3.org to test your code and fix it. Otherwise, you could always hire or consult a web developer. Source: over 1 year ago

HTTP/1.1 was such a game changer for the Internet that it works so well that even through two revisions, RFC 2616 published in June 1999 and RFC 7230– RFC 7235 published in June 2014, HTTP/1.1 was extremely stable until the release of HTTP/2.0 in 2014 — Nearly 18 years later. Before continuing to the next section about HTTP/2.0, let us revisit what journey HTTP/1.1 has been through. - Source: dev.to / 10 months ago

On the one hand, it just seems natural that "upstream" refers to the inbound request being sent from one system to another. It takes effort (connection pooling, throttling, retries, etc.) to make a request to an (upstream) dependency, just as it takes effort to swim upstream. The response is (usually) easy... Just return it... hence, "downstream". Recall the usual meaning of "upload" and "download". Upstream seems... - Source: Hacker News / about 2 years ago

To me it sounds like you’ve not solved this as the config you’ve mentioned is about preventing “illegal” (none RFC7230 ) requests, it isn’t really related to the problem you posted. Source: over 2 years ago

The program you are using to send data to the server may or may not automatically determine the right content-type header for your data, and knowing how to set and check headers is an essential skill. To learn more about the HTTP protocol check out the MDN guide or read the official standard, RFC 7230. - Source: dev.to / almost 3 years ago

It's neat, but I don't believe it is a compliant implementation of HTTP/1.1 (or 1.0). For example, it does not handle percent-encoded characters in the request URI.[1][2] [1]: https://datatracker.ietf.org/doc/html/rfc7230#section-3.1.1 [2]: https://www.w3.org/Protocols/HTTP/1.0/spec.html#Request-URI. - Source: Hacker News / almost 3 years ago
