Re: Block google page cache at firewall?

There are numerous representations --- notice i state representations
--- of a hexadecimal character. All depending on the utilization and/or
architecture.

i.e. 0xCD, 100Fh, %20 etc ...

Because L7 is an application level filter. All these representations
can be evaluated against. A URl is not exclusive to the hexdecimal
numbering system.

In the prevous examples these hexadecimal characters are denoted by a
designation digit(s).

i.e. 0x, h, %

Because these designation digits are not part of the hex character ---
they are simply there to denote to an object(person or applicaiton)
that the character is hexdecimally encoded. It points to the following
digits as a hex character. It neither adds or removes any value to the
encoded byte.

It is up to the end-user to explicitly declare a particular designation
digit for evaluation. That is why I refrained from explicitly
type-setting the "%" digit as a hexadecimal requirement.
