Response Types

Specify the list of Response Profile(s)for which this entry should be applicable.

Leave it Blank, to ignore this applicability test.

If one or more Response Profiles are specified, this entry will be applicable only after, response has been received from the web server.

To avoid application to a connection for specific Response Profile(s), use negation (!Response Profile).

Content type

Specify the MIME-type for which this entry should be applicable.

MIME-type is a way of identifying files on the Internet according to their nature and format.

Here, MIME-type indicates the response-body received from the server.

This entry applies to the regular expression matching the MIME-type.

Example : text/html, ^image/, ^application/, application/x-shockwave-flash.

If this entry should be applied to all responses, irrespective of MIME-type, leave it blank.

File Extension

Specify the file extensions for which this entry should be applicable.

This entry applies to the regular expression matching the extension of file(s) obtained in response body.

Leave it blank to apply all the requests, irrespective of file extension.

Transfer Encoding Chunk

This option is to control how the transfer encoding chunk header should be handled.
Example : Transfer-Encoding: chunked

  • ANY : Select this if transfer encoding chunked does not matter in response header.
  • NO : Select this if you don't want to apply profile if transfer encoding chunked present in response header.
  • YES : Select this if you want to apply profile if transfer encoding chunked present in response header.

multipart_byterange

This option is to control how the multi part/ byte ranges header should be handled.
Example: Content-type: multipart/x-byteranges; boundary=THIS_STRING_SEPARATES --THIS_STRING_SEPARATES
                 Content-type: application/x-pdf Content-range: bytes 500-999/8000 ...the first range... --THIS_STRING_SEPARATES
                 Content-type: application/x-pdf Content-range: bytes 7000-7999/8000 ...the second range... --THIS_STRING_SEPARATES--

  • ANY : Select this if multipart/ byterange does not matter in response header.
  • NO : Select this if you don't want to apply profile if multipart/ byteranges present in response header.
  • YES : Select this if you want to apply profile if multipart/ byteranges present in response header.

Response Header Pattern

Specify the regular expression matching the response header pattern for which this entry is applicable.

If left blank, applies to all response patterns.

Added Response Types

Subsequent applicable Entry may further modify the connection’s Response Profiles.
