It appears that AppEngine was choking on this http-header defined in appengine-web.xml: <http-header name="X-XSS-Protection" value="1" />
When I removed that, deployment succeeded. When I replaced the value with "1; mode=block", deployment succeeded. It doesn't appear to be the header name that causes the problem, as defining either of these headers in appengine-web.xml causes deployment to fail: <http-header name="pork-chop" value="1" /> <http-header name="pork-chop" value="2" /> But deployment still succeeds with either of these headers defined: <http-header name="pork-chop" value="a" /> <http-header name="pork-chop" value="0" /> I've got no idea what is behind these errors, so I'm just noting the details here in case others run into the same problem. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
