How can I send a double quote char using curl.exe in the -d parameter. I don't want to URL encode the double quote. Since the -d data needs to be surrounded in double quotes, I cannot seem to get it to work.
Or is there another flag for curl.exe that tells it to use a files contents for the whole form post data?
You can most certainly escape double quotes. How you do that depends on your operating system and shell, which you fail to specify. On Windows, you'd use the ^ as the escape character.
You can also do this:
curl [...] -d @filename
...which reads post data from a file called filename.
Google and/or man is your friend.
