To prevent the Web Agent from sending any proxy headers, blank out the ProxyHeadersUnprotected value. For example:
ProxyHeadersUnprotected=""
Note: To get a double quote character (") to appear, use a single quote ('). The Web Agent automatically converts it to a double quote.
The value, %% or %d (treated identically) may appear within a ProxyHeaders line. This value is replaced with either the smaller of the IdleTimeout and SessionTimeout multiplied by the ProxyHeadersTimeoutPercentage, or, if the timeouts are not set, the ProxyHeadersDefaultTime is used.
Ensure that values for the standard (1.1 and higher) and HTTP 1.0 headers are set properly for requests to the back-end server.
ExpireForProxy="YES" will expire cookie provider redirects carrying the SMSESSION cookie in the query string.
