Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Question: 

Why does www.whatismyip.com show information about Cisco WSA.

Environment:
Cisco Web Security Appliance

Symptoms:
Browsing to the site www.whatismyip.com reveals information about the Web Security Device.

www.whatismyip.com is a URL that can be used to find out the public IP address for a connection.

When users visit this website and the users are going through a Cisco Web Appliance,  it will display the Web Proxy information. This information may not be suitable for the customer environment.

What is My IP - whatismyip.com
Your IP address is: x.x.x.x
Possible Proxy Detected: 1.1
example.wsa.com:<Port#> (Cisco-WSA/a.b.c-ddd)

To make sure that www.whatismyip.com does not pick up the Web Proxy details, the VIA Header must be turned off on the Cisco Web Appliance. Once the VIA header has been turned off, the Web Proxy information will no longer be displayed.

The VIA header can disabled from the WSA WebUI:
Security Services > Web Proxy > Edit Settings > Headers > Request Side VIA > Do Not Send

After making this change, you should no longer see the WSA details on www.whatismyip.com
