8-6 Oracle Fusion Middleware Administrators Guide for Oracle Web Cache ■ Caching Reason : The reason that the object is cached or not cached. Possible values are: – ACL document: Cached or not cached because the object is an Access Control List ACL document for authorizing the access of a user to ACL-protected pages. – By caching rule: Cached or not cached because of a caching rule. – By ETag response header: Cached or not cached because of the ETag response header. – By HTTP headers: Cached or not cached because of information in the HTTP header. – By HTTP response code: Cached or not cached because of the HTTP response code. Normally any response code that is not 200 is not cached, but some non-200 responses can get cached because of a caching rule specifically allowing for it. – By reference TTL in ESI tag: Cached or not cached because of the nonzero value of the reference TTL time-to-live parameters specified in the ESI tag. – By Surrogate-Control response header: Cached or not cached because of information in the Surrogate-Control response header. – By X-Oracle-Cache response header: Cached or not cached because of information in the X-Oracle-Cache response header. – Cookie mismatch: Cached or not cached because the response contains a cookie that is not present in the request or that has a different value than the same cookie in the request. – No directive or rule: Cached or not cached because no directive or rule has stated that the object should be cached. – Not a GET or POST method: Not cached because the object was not a GET or POST method. – Object is too large: Not cached because the object is larger than the size specified as the Maximum Size of Single Cached Object specified in the Resource Limits and Timeout page. – POST body too large: Cached or not cached because the POST body was too large to be cached. – URL contains query string: Cached or not cached because the request contains a query string but the request did not match any caching rules. ■ Size : The column displays the size of the requested object. The size is represented in bytes, kilobytes KB, or megabytes MB. ■ Compressed?: This column displays the reason the object was compressed or not compressed: – Yes, by caching rule: Compressed because the object matched a caching rule that enabled or disabled compression. – Yes, by MIME type: Compressed because the objects MIME content type. – No, by default setting: Compression is enabled for the site and the browser accepts GZIP compressed response, but there is no matching caching rule and the response does not contain a compress control header in the Surrogate-Control response header or a MIME type.
