Please change the 'Accept GET from web.airdroid.com' to simply 'Accept from web.airdroid.com' (to accept all HTTP methods).
Much thanks, Thrawn, that fixed it!

This is the ABE ruleset I'm now using successfully, although I will yet tweak the regular expression a bit to account for our address allocation scheme.
