I'm using the YouTube API and they require a user to send an HTTP post with the 'data' of a video (title, description, etc) in XML format. I find the size of my xml using
length($xmldata);
and it returns me the correct number of bytes.
However, when I set up my headers for my post and include this content-length, it seems as if the content-length value is too high because I get the following when I run the script from the command line:
 % Total    % Received % Xferd  Average Speed   Time    Time     Time 
+ Current Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:--  0:00:42 --:--:
+--     0

...it's as if it is waiting for more data from me.
I tinkered with the content-length and found a good value where the post was accepted and went through perfectly, but I need my program to figure out this value.

Any suggestions on how content-length works in http headers and how I can get the correct value to send? I also tried opening/writing/closing a file and then doing a filesize on the file, but it's the same value as the perl 'length' function.

Thank you
