Proxo's Byte Limit...

[amy]

There's a 4K line-length limit in config files in general, a 4K limit on patterns, a 2K limit on URL matches, and a 260 limit on bounds matches. Raising them varies in difficulty from moderate to "rewrite the pattern matching engine" because there's assumptions on lengths in many places in the code, and blindly making the limits higher is likely to cause crashes instead.
