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

The latest edition of the #WebAlmanac by #HTTPArchive has been released: https://almanac.httparchive.org/en/2024/sustainability. The Sustainability chapter is full of great advice to reduce the carbon footprint of your website. Some observations from the report š§µ
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.
ā£ AVIF and JPEGXL is about equally efficient when it comes to byte reduction.
ā£ JPEG XL has better visual quality at the same byte saving ratio than AVIF
ā£ WEBP is great for smaller images, thanks to lower overhead than esp. AVIF due to the HEIC container.
ā£ Modern formats at the origin is almost not visible. <1%.
The 2024 Web Almanac has been published:

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
#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.
