Cisco ASA Series CLI Configuration Guide
Chapter 1 Configuring Clientless SSL VPN
Using SSL to Access Internal Servers
When configuring support for HTTP and HTTPS proxy services, you can assign preset credentials to
send with each request for basic authentication. You can also specify URLs to exclude from HTTP and
HTTPS requests.
Restrictions
You can specify a proxy autoconfiguration (PAC) file to download from an HTTP proxy server, however,
you may not use proxy authentication when specifying the PAC file.
Command Purpose

webvpn

Step 2
http-proxy and https-proxy
Configures the ASA to use an external proxy server
to handle HTTP and HTTPS requests.
Note Proxy NTLM authentication is not
supported in http-proxy. Only proxy
without authentication and basic
authentication are supported.

Step 7

provide basic, proxy authentication.
Step 10

do not specify an alternative value. The range is
1-65535.
