What are the longest HTTP header names and values? I dug into the HTTP Archive to find out: https://www.fastly.com/blog/the-lengthiest-http-headers #http #webperf #httpArchive

You might have read the 2024 edition of the #WebAlmanac and wondered how #jpeg_xl is doing....
I had a quick look into the ImageEngine data to see.
‣ AVIF and JPEGXL is about equally efficient when it comes to byte reduction.
‣ JPEG XL has better visual quality at the same byte saving ratio than AVIF
‣ WEBP is great for smaller images, thanks to lower overhead than esp. AVIF due to the HEIC container.
‣ Modern formats at the origin is almost not visible. <1%.

I have contributed to the chapters on accessibility and sustainability.

Is there anyone who recently configured HTTP Archive dataset on GCP BigQuery? I struggle to do so based one this guide: https://github.com/HTTPArchive/httparchive.org/blob/main/docs/gettingstarted_bigquery.md https://github.com/HTTPArchive/httparchive.org/blob/main/docs/gettingstarted_bigquery.md
If anyone can help, or run 1-2 queries for me, that would be fab! Thanks a ton!
Recently I've been building reports based upon HTTP Archive data. Rather than call BigQuery, I instead export the data I'm interested in into Parquet format and then query it locally on my laptop using DuckDB. Here's how I did it: https://discuss.httparchive.org/t/querying-the-http-archive-with-duckdb/2568
#httpArchive #parquet #DuckDB
And my favourite is:
Last-Modified: Invalid Date
... which was seen on 119 responses from the #httpArchive 2023-04-01 mobile run.
#http
Is this common? I queried the HTTP Archive and it found 121,058 double weak resources in the 2022-12-01 dataset with ETags that start with W/W/. That's 0.008% of all the resources. Good news: I found no triple weak validators.

#HTTPArchive says:
Over the previous year, the largest request was for a video, accruing 2080 kB on average per request.
Twenty. Hundred. Eighty. Kilobytes.
We have went backwards.
