Obtain URL Information in ASP. NET and JavaScript

The last time I saw a making sense of ASP. NET paths article about getting URL-related information in. net, I felt that the summary was very good, eliminating some of my fuzzy understandings. In the past, I used to look for the request documentation in msdn, but I am not clear about the differences between each attribute. Today I also want to sort out some common attributes and make a summary. If anything is wrong, please advise.

Let's assume that we access this address: http: // localhost: 1351/website1/DIR/default. aspx/adsf? Id = 12 # test. The return values of each method are as follows.
