455 Enabling remote access with clientless VPN
Identifying resources with URLs
Resource URL syntax
Clientless VPN uses standard extensions of URLs that are supported by browsers to represent Web
content.
About Web (HTTP and HTTPS)
Clientless VPN supports both secure and non-secure Web resources.
Note: Even though the slash (/) character is explicitly entered between the host and path elements of
the URL, it is considered part of the path.
■
Non-secure Web resource protocol: “http”
■
Secure Web resource protocol: “https”
Basic Web resources
The resources in the following table are configured and accessed using the modified URL syntax:
protocol://host/path.
Advanced Web resources
The security gateway’s advanced Web URL syntax, used in advanced rules, is the same as the standard
syntax supported by Web browsers. In addition to a host and path, the Web URL may also contain a
user name, password, and other supplementary information, such as query data.
The most typical form is either:
protocol://username:password@host:port/path?query
or:
protocol://username:password@host:port/path#fragment
where protocol is either http or https for Web resources.
The user name can appear without a password; however, password can only follow a user name.
The host identifies the IP address or fully qualified domain name (FQDN); when host appears without a
port, the default TCP/IP port for HTTP requests 80 is used. The :port denotes a way of accessing a Web
server running on a port other than the default.
■
/path is the absolute path name for a file system on the host.
■
?query contains information passed to a server program that generates dynamic content.
■
#fragment (anchor) points to a specific location on a Web page.
