anything Google not covered by another forum.

Well, I guess that's me.

Ponder these log selections. I've done pattern searches of saved logs; this is not a case of server hiccups (where Requests B and C are logged before Request A even though they came in later). The supporting files are genuinely getting requested before the page itself.

IPs are all different. Sometimes they are Googloid ranges like the one used by mobile-thingy-I-forget-its-name; more often they are not. UAs are not 100% Android, but far more often than not, say 5/6 of the time. I haven't fine-tooth-combed to see whether the residue are desktops or more obscure smartphones.

Observation #1: Stylesheets and page-specific scripts are requested before the page itself, with Google Search rather than the page as referer.

Observation #1a: These CSS and JS files are requested even if
--the page itself ends up not being requested at all, or
--the page is requested but is redirected to a directory that uses a different set of stylesheets (it was this that first made me aware of the phenomenon)

Observation #2: This is an http site, meaning that query details (the referer's query string) are normally suppressed in the referer. In some but not all cases, these premature requests for CSS and JS include the full search term.
