Problem attempting to use Apache 2.2 mod_proxy_http and mod_shib w/ShibUseHeaders simultaneously

[Steve Siirila]

Just a quick followup...  the issue was in the application which was
silently discarding all header variables upon reaching one without a
value.  And apparently either the Shib SP or the proxy likes sending
value-less header variables (e.g. "Shib-AuthnContent-Decl:") the moment
ShibUseHeaders got turned on.  Now that the application ignores these and
reads the rest it eventually gets to the last few, including the critical
one (Content-Length:).

(I hadn't gotten back to this in the past two weeks or I'd have realized
this sooner.)
