Detecting Headless Browsers, Briefly

Sample post — placeholder content for crawl-diversity testing only.

Automated HTTP clients and headless browsers often differ from ordinary human browsing sessions along several observable dimensions: navigation properties exposed to page scripts, timing and ordering of resource requests, the presence or absence of certain browser-only APIs, and inconsistencies between the declared user agent and the actual runtime behavior.

None of this is specific to any real product — it's generic background useful only as filler content for this test fixture. See the docs page for the structural notes that actually matter for this site, or continue to the next post.
