Something is causing the 'ETag' headers produced by the "public" RESTBase (queried directly from the client) to be mangled or lost. My theory is that some proxy or browser extension is doing that. When we detect a bad etag when fetching the page contents, discard the result and try querying the "private" RESTBase via the MediaWiki API (similar to what we do on private wikis, except there we talk directly to Parsoid instead of RESTBase). After I463a84de63, that returns the etag as part of the payload rather than HTTP headers, and should pass unharmed through whatever is mangling the data. Also compare and log the two etags.
