Block, Allow, or Redirect Transaction Requests
The web proxy controls web traffic based on the policies that you create for groups of transaction 
requests.
Allow. The Web Proxy permits the connection without interruption. Allowed connections may not 
have been scanned by the DVS engine. 
Block. The Web Proxy does not permit the connection and instead displays an end user notification 
page explaining the reason for the block.
Redirect. The Web Proxy does not allow the connection to the originally requested destination 
server and instead connects to a different specified URL, see 
.
Note
The preceding actions are final actions that the Web Proxy takes on a client request. The Monitor action 
that you can configure for Access Policies is not a final action. 
Generally, different types of policies control traffic based on the transport protocol. 
Note
Decryption policy takes precedence over Access policy.
Client Applications
About Client Applications
Client Applications (such as a web browser) are used to make requests. You can define policy 
membership based on client applications, and you can specify control settings and exempt client 
applications from authentication, which is useful for applications that cannot prompt for credentials.
