Disabled control characters in URIs. Control characters (0x00-0x1f, 0x7f) were never allowed in URIs, and must be percent-encoded by clients. Further, these are not believed to appear in practice. On the other hand, passing such characters might make various attacks possible or easier, despite the fact that currently allowed control characters are not significant for HTTP request parsing.
