The old xp_get_content_length() only checked five hardcoded case variants (Content-Length, Content-length, content-Length, content-length, CONTENT-LENGTH), which did not comply with RFC 3261 requiring case-insensitive header matching. Replace with get_header() which uses strcasestr() for proper case-insensitive search and already handles the compact form "l:".
