Subject: [PATCH] Tuning cache controls.  In Chrome a reload sets the request
 header to max-age=0, but still includes an If-None-Match header.  That means
 we sould not depend o a cached ETag, which we don't in any case.  A
 shift-reload on the other hand sets the header to no-cache and does not
 include an If-None-Match header, meaning this is not a conditional get at
 all.
