I think my problem is either with urlencoding or a lack of knowledge
on HTTP headers.
I want to ask about the second.
I think the problem is with newline characters.
Is this correct that when I open the @file with vi it says "incomplete
last line"?
another question (if it is not the correct place to ask, forgive me)
is about extracting _VIEWSTATE
variable from html. I see '^M' character when I open it with vi. I
think,know that this must
be removed. Therefore I use commands (before urlencoding) like
tr -d "\015" < foobar > foobar2
tr -d "\n" < foobar2 > foobar3
tr -d "^M" <foobar3 > foobar4
for removing newlines and ^M's from the variable.
Is this correct?
I am determined to solve this problem and keep on struggling.
