by 27 comments

Apache .htaccess and httpd.conf have the power to send and manipulate HTTP Header Requests and responses like sending P3P privacy headers, Content-Type: UTF-8, Content-Language: en-US, etc. The power is immense and you can do some really cool stuff with HTTP Headers!

Custom HTTP Headers

Any time you see a meta tag of type "http-equiv" you can replace it with a real header in htaccess

100% Prevent Files from being cached

This is similar to how google ads employ the header Cache-Control: private, x-gzip-ok="" to prevent caching of ads by proxies and clients.


FileETag None

Header unset ETag
Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
Header set Pragma "no-cache"
Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"


Remove IE imagetoolbar



Header set imagetoolbar "no"


Add P3P Privacy Headers to your site

Adding a P3P header to your site is a good idea, do this.


Header set P3P "policyref="/w3c/p3p.xml", CP="NOI DSP COR NID CUR ADM DEV OUR BUS""

# OR THIS, SIMPLER
Header set P3P "policyref="/w3c/p3p.xml""

Add a "en-US" language header and "UTF-8" without meta tags!

Hacking and Hackers

The use of "hacker" to mean "security breaker" is a confusion on the part of the mass media. We hackers refuse to recognize that meaning, and continue using the word to mean someone who loves to program, someone who enjoys playful cleverness, or the combination of the two. See my article, On Hacking.
