 ### `test_compressed_resources.sh`
 
-TBD
+Bash script `test_compressed_resources.sh` tests one or more resources for HTTP Compression:
+
+```Shell
+$ $BIN_DIR/test_compressed_resources.sh -d /tmp/out $url1 $url2
+2017-06-11T13:20:39Z INFO test_compressed_resources.sh BEGIN
+2017-06-11T13:20:39Z INFO test_compressed_resources.sh requesting (compressed) resource: http://md.incommon.org/InCommon/InCommon-metadata-preview.xml
+2017-06-11T13:20:43Z INFO conditional_get reading cached content file: /tmp/http_cache/1e6b844a49d1850b82feded72cf83ed7_content

+2017-06-11T13:20:46Z INFO test_compressed_resources.sh END
+```
+
+The script produces a JSON array containing objects such as the following:
+
+```JavaScript
+  {
+    "successFlag": true,
+    "message": "Integrity of compressed metadata confirmed",
+    "location": "http://md.incommon.org/InCommon/InCommon-metadata-preview.xml",
+    "ResponseCode": "200",
+    "Date": "Sun, 11 Jun 2017 13:10:37 GMT",
+    "LastModified": "Fri, 09 Jun 2017 19:05:16 GMT",
+    "ETag": "\"80bc05-5518ba65a1fd5\"",
+    "ContentLength": "8436741",
+    "ContentType": "application/samlmetadata+xml",
+    "ContentEncoding": "gzip"
+  }
+```
+
+Like the previous script, this script also depends on cached metadata. In addition, this script requests each (compressed) resource from the server just-in-time. See the inline help file for details:
+
+```Shell
+$ $BIN_DIR/test_compressed_resources.sh -h
+```
