Column	Description
Name	The custom pattern or exclusion pattern name
Description	The custom pattern or exclusion pattern description
Custom pattern or exclusion pattern type	Select the extractor type from the drop-down
RegEx	Header
TextDelimited	JPath
Text Before	A text delimiter that occurs immediately before the value to be extracted.
Text After	A text delimiter that occurs immediately after the value to be extracted.
Regular Expression	The regular expression with a single value <val> which will be extracted. Example: \w+\d="(?<val>.+)" returns a value of the name/value pair, where the name ends with a digit.
Header	The response header name, selected from the drop-down
JPath query	Enter JPath query to extracts a value from a JSON response
Content-Type	Content-Type(s) for which this custom pattern or exclusion pattern applies. Separate multiple entries by ",".
Extractor Page	Page URI or wildcard for which this custom pattern or exclusion pattern applies.
Use HTML Decoding?	To apply HTML-decoding to the Extractor value, select Yes. Example of HTML-decoding: converting "&>" to ">". The default is No.
Use URL Decoding?	To apply URL-decoding to the Extractor value, select Yes. Example of URL-decoding: converting: "%3F" to "?". The default is No.
Enforce URL encoding?	The default is No. When using an extractor in a parameter, StresStimulus automatically URL encodes its value when necessary. Select Yes to enforce the URL encoding of the extractor's value. Use this option with caution as it can result in double-encoding a parameter.
Use Base64 Encoding?	To apply Base64 encoding to the Extractor value, select Yes. The default is No.
Use Escaped Hex Decoding?	To apply escaped hex decoding to the Extractor value, select Yes. In a response, some special characters may be escape hex encoded. An example of decoding: '\x23' to ''. The default is No.
Group number to extract	Enter a group number in the regular expression that will render the extractor value. For example, in this regular expression. (\d{3}):(\w+) enter 1 to extract the 3 digit number or enter 2 to extract the word.
Parameter Creation Mode	By default, a pattern creates necessary parameters from extractor value. To use a different parameter format, select Formatted.
Parameter Page	Page URI or wildcard for which a parameter will be created.
Parameter Name	Web form field or query sting parameter name.
Parameter Format String	To surround the parameter with text, use format string <text before>{0}<text after>. Example id={0}
Disabled?	Select Yes, to disable the custom pattern or exclusion pattern. The default is No.
