Hit processing
The following table describes the hit processing settings.
Setting | Description |
---|---|
Include Raw Request |
Determines whether RawRequest is on. RawRequest is an aid in debugging. The
default value is False (disabled). If enabled
(True ), the HTTP Request headers are added to the hit.
Note: Discover highly recommends that this value can
set to False ; otherwise data is added to each
hit. |
Include Response Headers |
Determines whether ResponseHeaders are on. ResponseHeaders are aids in
debugging. The default value is False (disabled). If
enabled (True ), the HTTP Response headers (in Discover format, not necessarily the exact HTTP
representation) are added to the hit.
Note: Discover highly recommends that this value stay
set to False ; otherwise data is added to each
hit. |
Decode URL fields |
This option determines whether to URL-decode URL fields. |
Cookie Parser |
If this option is selected, a cookies section is added to the request. |
Enable UnReq Cancelled |
If enabled, this option checks the last 100
bytes of the response body for </html when capturetype=1 and
marked as canceled. |
Inflate compressed response |
When this option is selected, responses are
automatically inflated in the DNCA pipeline. If a response has a content-encoding
header whose value is deflate , gzip ,
or x-gzip , then it is a candidate for having the
body that is inflated from its compressed state. If this option is
selected, then an attempt is made to inflate the response. Note: This
setting must be set to false . Enabling this feature
can significantly increase the data volume that is transmitted between
the Unica Discover Network Capture Application server
and the Transport Service.
|
Preserve responses when inflate fails |
When a hit response is inflated and the inflate process fails, the response is replaced with HTML reporting that an inflate error is occurred. Select this option to disable the replacement HTML, which preserves the original response. |
Deflate hits sent to target recipients |
Select this option to deflate hit responses before they are sent to a target recipient. The hit responses are compressed by using the HTTP deflate method. Enable this option to reduce the amount of network bandwidth that is used to deliver Discover hits to the Discover Transport Service. |
Enable I18N |
When selected, internationalization support is enabled on the DNCA. The
request urlfields are encoded to UTF-8, and an attempt is made to detect
the response body encoding. Note: There is a known issue in which
special characters submitted in JSON data from a Discover client framework are mangled. |
Delete Images on DNCA side |
When enabled, this option deletes image hits in the capture stream that meet specific criteria. See Delete Images on DNCA Side. |
Max Response Size |
The largest acceptable response size (in bytes).
The default value is 1572864 (1.5 MB). |
Default Response Encoding |
If the DNCA is not able to detect the encoding type of a response, this value is used. |
Default Request Encoding |
If the DNCA is not able to detect the encoding type of a request, this value is used. |
Total dropped due to ICU encoding errors |
This statistic reports each time a hit (either Request or Response) cannot be encoded to UTF-8 which causes the complete hit to be dropped. This scenario also generates an error (ERR) in the log. |
