调研方向
未识别出 repository 文件或测试。首先针对一个 SQLite 文件重现向 GitHub Pages 发出的 HEAD 和 Range 请求，然后比较 content-encoding 和 content-length 标头；当确认提供服务的行为并记录受支持的变通方案后，调查即告完成。
由索引模型根据 Issue 内容生成。
描述
I have been using GitHub Pages to serve SQLite database files for a client-side app with sql.js-httpvfs, which requires HTTP Range requests to read parts of the database file.
Until recently, this setup worked correctly. However, now the sql.js-httpvfs worker throws an error:
Length of the file not known. It must either be supplied in the config or given by the HTTP server.
Upon inspecting the HTTP response headers, I see that HEAD requests respond with content-encoding: gzip. According to sql.js-httpvfs, this breaks range requests because the server returns compressed data on HEAD but serves uncompressed data on range requests, making the byte length calculation incorrect.
Example response headers from a HEAD request:
content-encoding: gzip accept-ranges: bytes content-length: 1288
This behavior causes sql.js-httpvfs to fail when trying to read the file size and ranges properly.
Could you please confirm if there has been a recent change in how GitHub Pages serves static files or handles gzip encoding on HEAD and Range requests? Is there a recommended workaround to properly serve files that need range requests without gzip interfering?
Thank you very much for your help!
