Communication and Proxy view

Communication and Proxy (if AppScan needs a proxy to access the tested application) view of the Configuration dialog box.




Number of Threads

Set the maximum number of requests that will be sent simultaneously.

By default this is set to its maximum possible value of 10. If your site does not allow simultaneous threads reduce this number to 1.

Adjust timeout automatically

In some case you may be able to reduce the length of the scan by selecting Adjust timeout automatically during the scan. When selected AppScan reviews and adjusts the timeout automatically throughout the scan, which may significantly reduce scan length.


If the above check box is cleared, you can set the time limit (in seconds) for AppScan® to wait for a response from the web server. By default, a timeout of 10 seconds is used.

Request rate limit

By default, AppScan sends its requests to the site as fast as possible. If this overloads your network or server, or if your site limits users to a maximum request rate, select this check box and reduce the limit.
  • If Action-Based Explore is used (Scan Configuration > Explore Options > Explore method), this setting affects only the Test stage of the scan
  • If Request-Based Explore is used, this setting affects both the Explore and Test stages of the scan
