Having ongoing discussions about URL parsing differences as a basis for a #curl security vulnerability report made me check when I wrote my "my URL isn't your URL" blog post.

*Nine years ago*. And we have not made a single move towards a solution in all this time.

My URL isn’t your URL

When I started the precursor to the curl project, httpget, back in 1996, I wrote my first URL parser. Back then, the universal address was still called URL: Uniform Resource Locators. That spec was published by the IETF in 1994.

Digital Extremes violate the #cURL license?

If they do, that's a shame but there's not a lot I can do. Anyone who can verify this claim? (probably by scanning the binaries for known names or similar)

Hi, I just want to let you know (and have there be a record) of the fact that Digital Extremes, a Canadian video-game-developer-turned-GaaS-developer, are using cURL (statically linked alongside Op...

Today is exactly twelve years ago since we created the lib/http2.c source file in the #curl source tree, and doing HTTP would never be the same again.

The paradigm shift going from one transfer per connection to possibly multiple transfers per connection was massive and took many years until most of the bugs were ironed out.

We are thirteen days away from next #curl release.

We have 17 changes and 225 bugfixes logged so far for this.

One low severity CVE will be published in sync with this release.

Thanks for flying curl.

Today we celebrate seven years of #curl shipping official Windows executables, thanks to @vsz's awesome work.

Blessed curl builds for Windows

The curl project is happy to introduce official and blessed curl builds for Windows for download on the curl web site. This means we have a set of recommended curl packages that we advice users on Windows to download.

Inspired by the BBC Tech report from @tdp_org, I looked at Wikipedia.

Yesterday, Wikipedia received over 45 million requests made with curl, from 113 distinct curl releases.

Of these, 32 million use the default UA (e.g. curl CLI). The other 13 million embed libcurl with a longer UA string containing curl (e.g. GuzzleHttp/PHP, PycURL, UnityPlayer)

At 12 million, most are curl/7.88.1.

Raw data, queries, and scrub/cleaning parameters:

Yesterday we saw 161 different versions of #curl make just over 1 million requests to www.bbc.co.uk & www.bbc.com.

The oldest version is 7.0.0 (1 request).
The newest version is 8.15.0 (18,969 requests).

I'd spotted a load of different cURL versions in something else so was curious how many versions we see.

Screenshot of the Google BigQuery web UI which shows a table of results for a query over yesterday's access logs where user-agent like "curl/%". There's a total of 1,010,489 requests. curl/7.29.0 is the most popular version with 129,825 requests.
