I am trying to create a really simple proxy using PHP.

Basically, i need to:

1. read in the contents of a URL.
2. get the content-type
3. set the content type for the response
4. write the contents of the URL to the response.

here is what i have thus far:

$dataURL = "http://www.foo.com/data.xml";;
$fp = fopen($dataURL, "r");
$content = fread($fp, true);

I am running into two problems. One, the second param for fread takes 
the size of the file / content. how do i get this?

there is a comment at:

which says to just specify a constant and it will work, but what ever 
number i specify, that is the amount of data that is read.

how do i retrieve the content type?

thanks for any help...
