Report the longest stretch of one character repeated back to back in a request line.

today's brief

July 2001. Code Red hits Microsoft IIS with a request whose URL is one long unbroken line of the letter N, far more of it than the buffer behind it could hold. Nobody was subtle about it. In under 14 hours the worm had 359,000 machines and was defacing their pages, and whitehouse.gov moved to a new address to duck the flood it aimed there. Measure the longest run in a request line.
