Hi all, I have a few questions about using VRT_SetHdr function. I'm sure some of this is due to lack of c experience so I apologize if this is the case.
Firstly, Is there a way to create the header string dynamically. I know the header string has to be in the format "\020X-Forwarded-For:", it has to start with the length of the string in octal, But if I'm creating the header name dynamically, Say if i wanted to create separate headers based of GeoIP data or something similar, How could I go about creating the string so It matches the format? I've tried to overwrite the first byte of the header string to be the length of the rest of the header string as an unsigned int, which will work to the extent that Varnish passes all of the asserts it and will display the page correctly, But the header itself will be incorrect, it seems like the browser is trying to convert the integer to a char and ends up just displaying and an empty box and the string itself. And secondly, purely out of interest, Could someone explain why the header is prefixed with its length in octal? Does it have something to do with correctly setting the amount of memory needed?
