Re: [Users] UDP Fragmentation (again)

Hi, Yes, I've started to clean up the headers from cisco, but I do agree that som generic "compression" function wuld be nice to have. As long as all crucial information is kept.

Is there really a way to use compact format withing the script (without regexp textops)?
