- 1st pass at documentation with the README. - Attempt to detect trivial redirect loops. - Loosen the request parser enough to just accept URLs, so you can easily test rewrite behavior by just running volta and pasting URLs. - Alter the whitelist "negative" rule syntax to more closely match normal rules. Rename references to negative rules from "whitelist" rules, to avoid confusion.
Ignore whitespace changes - Everywhere: Within whitespace: At end of lines:
