≤GB≥Hypertext Transfer Protocol (HTTP) - Proxy≤P≥
The protocol used to transfer web pages on the World Wide Web, defined in ≤U2≥RFC 2068≤P0≥ and ≤U2≥RFC 1945≤P0≥. The default TCP port number for HTTP connections is port 80.
This TCP probe lets you test that a web server can be accessed using a remote proxy server as an intermediary. For example, this probe can check if your web server is accessible from some remote location on the Internet (e.g. www.proxymate.com).
≤i≥URL≤p≥ is the full URL to the desired page on the web server,including the “http://” scheme (e.g. “http://www.intermapper.com”)
≤i≥Proxy User ID≤p≥ is your user ID for the proxy server. Leave this field blank if no authentication is required to use the proxy server.
≤i≥Proxy Password≤p≥ is your password for the proxy server. Leave this field blank if no authentication is required to use the proxy server.
≤i≥String to verify≤p≥ is a string to verify in the data returned by the HTTP server. For example, if you are retrieving a web page, you might search for “<HTML>” or “<P>” to verify that the data is HTML.
≤i≥User Agent≤p≥ is the string that identifies this InterMapper client probe to the proxy web server. Some proxy servers block traffic at the proxy based on the User-Agent identity. This parameter lets you optionally override InterMapper's default User-Agent setting. If you leave this parameter blank, InterMapper sends a User-Agent string of “InterMapper/version”, where version is the current version number of InterMapper.
