If you type an Internet URL (Uniform Resource Locator) which begins with http: or https: at the prompt, TCC will pass the URL to Windows. Normally Windows will start your web browser, and request that the browser retrieve the page pointed to by the URL. This feature will only work if Windows can find the proper association between the http: or https: prefix and the browser software. While this association is standard for most browser installations, it may not be present on all systems.
The ability to "start" URLs in this way is restricted to those beginning with http: or https:. Other standard prefixes such as ftp:, mail:, and news: cannot be started directly from the prompt; you must enter these URLs directly into your browser.
HTTP and HTTPS addresses in Take Command and TCC will have any embedded spaces converted to "%20" before sending the URL to the server.
See Waiting for Applications to Finish for information on problems with waiting for the browser to finish after starting a URL.
