I posted this question about half an hour ago: What's the difference between using Url.Content and not doing so?
After the first answer, I quickly realized my ignorance (and that my question was poorly constructed). Now I feel like editing the question heavily to be more specific about what I wanted an answer for, also to make it relevant to others in the future.
There's already an answer there that tells me I'm wrong, trying to explain the "~"-symbol which I didn't actually ask about (since I know it).
If I edited it, it could mean that the answer provided becomes odd/irrelevant. On the other hand, I might get some more precise answers.
