Exclude Strings or Content Types from the Correlation Scan

By default, the correlation engine scans all plain and html text searching for correlations. Some of the candidates found may not be real correlations. To enhance correlation accuracy, you can configure VuGen to ignore certain text strings, regular expressions, or content types.

  1. To exclude a specific text string

    1. Select Record > Recording Options > Correlations > Configuration.

    2. Click the button adjacent to Excluded strings.

    3. Click the button to open the Add string to exclude dialog box.

    For example, enter getCachedId to exclude the string getCachedID as a correlation candidate.

    1. Select Record > Recording Options > Correlations > Configuration.

      Click the button adjacent to Excluded strings.

    2. Click the button to open the Add string to exclude dialog box.
    3. Enter a regular expression and check the Regular Expression box or select the button to view and select from a list box of regular expression character classes and complete the regular expression.

    For example, enter ^navurl:.* to exclude strings such as navurl:\\any_char, navurl:1234 as correlation candidates..

  3. To exclude content types

    1. Select Record > Recording Options > Correlations > Configuration.
