void http_all_headers( )

Set all headers used by a normal page load.

void http_caching_headers( [boolean $p_allow_caching = false])

Set caching headers that will allow or prevent browser caching.

Parameters

boolean

$p_allow_caching

Allow caching

void http_content_disposition_header( string $p_filename, [boolean $p_inline = false])

Send a Content-Disposition header. This is more complex than it sounds

because only a few browsers properly support RFC2231. For those browsers which are behind the times or are otherwise broken, we need to use some hacky workarounds to get them to work 'nicely' with attachments and inline files. See http://greenbytes.de/tech/tc2231/ for full reasoning.

Parameters

string	$p_filename	Filename
boolean	$p_inline	Display file inline (optional, default = treat as attachment)

void http_content_headers( )

Set content-type headers.

void http_custom_headers( )

Load and set any custom headers defined by the site configuration.

void http_security_headers( )

Set security headers (frame busting, clickjacking/XSS/CSRF protection).

boolean is_browser_chrome( )

Checks to see if the client is using Google Chrome so we can enable quirks and hacky non-standards-compliant workarounds.
