Questions about joinroot-cms-preview.herokuapp.com
- How does PageSourceSearch know what joinroot-cms-preview.herokuapp.com is built with?
- From the site's own source code. The crawler stores the exact bytes of its pages and first-party scripts; the libraries are recognised by fingerprinting that code against known releases, the identifiers are read out of the tag snippets, and the third-party hosts are the script, iframe and stylesheet sources in the HTML and the absolute URLs inside the scripts. Nothing is inferred from headers or guessed.
- How far back does the history of joinroot-cms-preview.herokuapp.com go?
- To the first crawl the timeline lists. Every crawl records what the site looked like; when a file's content changes, its earlier version stays viewable because the stored chunks are never deleted, only mapped. A crawl that finds a file unchanged adds no copy.
- Can I see an older version of a script from joinroot-cms-preview.herokuapp.com?
- Yes. In the stored files list, every date under a file opens the version that was live at that crawl, with the same viewer as the current one. The raw bytes can be downloaded from there.
- Which other websites use the same tracking IDs as joinroot-cms-preview.herokuapp.com?
- Each identifier links to its reverse lookup, the list of every site in the index whose source carries the same id: the sites one analytics property or tag manager container is shared across.
Look up another site, browse sites by tracking ID, third-party host or technology. Site owners: see the crawler page for how stored pages are removed.
