We know how many times the "Download as PDF" link is clicked per day and how many PDFs are downloaded per day, but we don't know which browsers users are using to make these requests. Let's test the hypothesis that users are using older browsers with little or no PDF support to download PDFs.
This data should be available in [[ https://wikitech.wikimedia.org/wiki/Analytics/Data_Lake/Traffic/Webrequest#wmf.webrequest | the `wmf.webrequest` table ]].
== Outcomes
[] We understand and document the range of browsers that are being used to download PDFs rendered by the Electron render service.
- It should be documented as a sub-page of [[ https://www.mediawiki.org/wiki/Reading/Web/PDF_Functionality | mw:Reading/Web/PDF_Functionality ]].
== Notes
1. ~~AFAIK the PDF download URL is [[ https://github.com/wikimedia/mediawiki-extensions-ElectronPdfService/blob/833964efb7440d0850d5406308fc5b90edda1054/src/ElectronPdfServiceHooks.php#L90-L99 | /wiki/Special:ElectronPdf?action=redirect-to-electron ]]~~
@phuedx: In T176467#3640968, @Jdlrobson points out that it's /api/rest_v1/page/pdf.
