HTTP Client Identification
Whenever a Vuser sends a request to a web server, the request always includes
an HTTP header. The first line of text contains a verb (usually "GET" or "POST"),
the resource name (for example "pclt/default.htm"), and the version of the protocol
(for example "HTTP/1.0"). Subsequent lines contain "header information" in the
form of an attribute name, a colon, and some value. The request ends with a blank
line.
All web Vuser headers include a "user-agent" header that identifies the type of
browser that is being emulated. For example,
User-Agent: Mozilla/3.01Gold (WinNT; I)
identifies the Browser as Netscape Navigator 3.01 running under Windows NT on
an Intel machine.
You can specify that a Web Vuser emulate any of the standard browsers.
Alternatively, you can specify that each Vuser emulates an HTTP client that is not
in the list of supported browsers. In this case, you must supply a custom user-agent
string that is included in all subsequent HTTP headers.
