Tracking ID 694-81: General Limitations of Web Agents

CA DataMinder web agents (Client Network Agent, ICAP agent, and the Network Appliance) have some limitations when attempting to control data submissions from certain sites.

• Some web applications can cause multiple intervention actions to be applied when CA DataMinder detects a policy violation. Typically, this happens with applications that use client-side JavaScript, or technologies such as AJAX to submit data to the web server. CA DataMinder web agents attempt to block such submissions by failing the HTTP request, but if the client-side part of the web application does not handle the failure well, it resubmits the data, resulting in multiple violations.

  Note: The Network Agent attempts to minimize the impact on the user by keeping a history of recent interventions, quietly failing subsequent requests if they appear to be resubmissions and the original was blocked.

• Some web applications, for example Google Docs, upload fragments of data rather than whole files. This can lead to incorrect policy application because if CA DataMinder does not have access to the whole file, it cannot make a correct decision. Consider using policy to block access to such problem sites.
