This article was previously published under Q322604



SYMPTOMS
Proxy 2.0 sends an HTTP 304 (&quot;Not modified&quot;) response back to a client that is requesting an update of a Web page if all of the following conditions exist:
 * The &quot;If-modified-since&quot; time is older than the cache copy.
 * The cache copy is expired.
 * The data has not been modified since the &quot;If-modified-since&quot; time of the cache copy.

In the first criterion, the client should receive the cache copy because it is a newer version. However, the proxy server does not send that copy.
