Capitalization (Case Sensitivity) of URLs
By default the Netsparker scanners do not differentiate between uppercase and lowercase URLs. Therefore both the below URLs are considered as the same URL:
http://example.com/dir/index.php
http://example.com/DiR/IndEX.php
If you want to change this behaviour tick the option Case Sensitive from the Scope node in the Scan Policy as shown in the below screenshot.
