[ale] Data encoding in a web page

[Christopher Fowler]

I'm sure it happens on post requests in this case because I've got
a middle man running and I can see it.  What I do not understand is
how netscape knows to encode it. 

As fasr as asii is concenred, what is the difference between

"dDwyMTQxMjc4NDIxO3Q8O2w8aTwxPjs%"
and
"Bob Smith"
