| // UrlMatcher is a class to manage the list of URLs stored in the field trial |
| // param. As the original data from the field trial params is delivered as a |
| // special format string, this class parses and formats it, and stores the list. |
| // |
| // The expected param format is a comma separated string, and each string is |
| // separated by the vertical bar. The left side of the vertical bar is a |
| // host name, and the right side is a part of path or search params. |
| // |
| // The string is something like |
| // "https://test.exmaple|/foo,http://another.test.example|?foo=bar,https:://yet.another.test.example" |
| // Then the UrlMatcher will parse it to the formatted list like |
| // [ |
| // ["https://test.example", "/foo"], |
| // ["http://another.test.example", "foo=bar"], |
| // ["https:://yet.another.test.example", ""] |
| // ] |
| // Based on the above list, UrlMatcher::Match() checks 1) if the given url is a |
| // same origin or not, 2) if it's a same origin, check the second value in the |
| // list item. If it's an empty string, that means origin-level url matching. If |
| // it has a string, check the path string and query string in the given url |
| // contain it or not. |
