svn commit: r680893 - /incubator/shindig/trunk/java/gadgets/src/main/java/org/apache/shindig/gadgets/servlet/ConcatProxyServlet.java

Author: lryan

New Revision: 680893

URL: http://svn.apache.org/viewvc?rev=680893&view=rev
Log:
Suppress writing all headers in the Concat servlet and explicitly set the 
expiration and content disposition instead of delegating to ProxyHandler. The 
prevents writing headers for each concatenated part which can upset some 
servlet engines once the response headers are committed.
