Configuring Advanced Settings in Acunetix

By default, Acunetix comes built-in with settings that are designed to work in the vast majority of websites and web applications. Of course, you can customize a Target’s settings, but there might be cases where you need very fine-grain control on your Target settings.

Fine-grain scan controls can be customized from the Acunetix Settings.xml file which is stored in C:\ProgramData\Acunetix 11\shared\General\Settings.xml

Open the XML file using a text editor of your choice. You will need Administrator privileges on the machine Acunetix is installed on, in order to modify the XML file.

While modifying settings, please take care to stop the Acunetix and Acunetix Database services (using the Task Manager, or command-line).

The following options are some of the most useful settings you may wish to modify. While there are many more configuration options exposed by the XML file, the following are the most common and the most useful advanced settings you may wish to modify.

/Settings/ScanSettings/Extensions File Extension Filters Specify the type of files (by file extension) to be included/ignored by the crawler. Please note that binary files such as images, movies and archives are excluded by default to avoid unnecessary
traffic.
/Settings/ScanSettings/Parameters/ParameterManipulation/HTTPHeaders/Headers Custom HTTP Headers Specify custom HTTP Headers that the crawler and scanner should include with the other standard HTTP headers

/Settings/ScanSettings/Crawler/MaximumNumberOfPagesToCrawl Crawler file limit Configure the maximum number of files the crawler should crawl
