This site permits a user both to explore the parsing of a web URI and to see what happens when the corresponding resource is requested.
To explore URI parsing, check Show URI Information but do not check Show URI Web Data. With these settings, the URI may be valid or be complete nonsense entered simply to test the parsing rules.
To explore the text content or image data downloaded as part of a web response, check Show URI Web Data. Optionally, check Show URI Information to examine how the URI is being parsed.
When information is requested, status codes and possible error codes are displayed as well as other information about the content.
The application is activated either by clicking the button or by pressing return in the Web URI text box.
