| 1960 | | | | | # SCRIPT_NAME=/path/to/env.cgi |

| 1971 | | | | | # if $REQUEST_URI and "$SCRIPT_NAME$PATH_INFO" only differ by the number |
| 1972 | | | | | # of consecutive /. |
| 1973 | | | | | # |
| 1974 | | | | | # So for instance, in: http://foo/x//y/script.cgi/a//b, we'll return a |
| 1975 | | | | | # script_name of /x//y/script.cgi and a path_info of /a//b, but in: |

| 1978 | | | | | # script_name == /foo/x/z/script.cgi and path_info == /b/c. |
