Suppose one URL encodes a string.
urlencode(String1); => Becomes String2
Does successive url encoding on String2 create a string that is different from String 2?
meaning, urlencode(String2) == String2 ?
urlencode(String2) != String2 ?
It certainly does create a different string, if the original string contained any non-alpha and non-
-_character.So, if the first
urlencodeencodes even one non-space, it will put a%in the resulting string as part of a%XXpattern. Subsequenturlencodes will re-encode that%(and start mangling your original string beyond recognition).See it in action.
