Tutorial Append / Prepend Files

by in , 0

Rather than having to call / include a file you need on every single page, you can have them automatically prepended (top of file) or appended (bottom of file) automatically through your .htaccess file.

php_value auto_prepend_file "/real/path/to/file/functions.php"
php_value auto_append_file "/real/path/to/file/footer.php"

by in , 0

This code is useful for multi environment setups (staging, production, etc.) it allows you to keep your htaccess files in sync while maintaining an htpasswd on your development environment or anything but the live environment.

#allows a single uri through the .htaccess password protection
SetEnvIf Request_URI "/testing_uri$" test_uri

#allows everything if its on a certain host
SetEnvIf HOST "^testing.yoursite.com" testing_url
SetEnvIf HOST "^yoursite.com" live_url
Order Deny,Allow

AuthName "Restricted Area"
AuthType Basic
AuthUserFile /path/to/your/.htpasswd
AuthGroupFile /
Require valid-user

#Allow valid-user
Deny from all
Allow from env=test_uri

Tutorial Active Gzip Compression

by in , 0

Compression reduces response times by reducing the size of the HTTP response. Gzip is the most popular and effective compression method currently available and generally reduces the response size by about 70%. Approximately 90% of today's Internet traffic travels through browsers that claim to support gzip.

# BEGIN GZIP
<ifmodule mod_deflate.c>
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript
</ifmodule>
# END GZIP

Tutorial 301 Redirects

by in , 0

This is the cleanest way to redirect a URL. Quick, easy, and search-engine friendly. Remember HTAccess stuff is for Apache servers only.

Redirect a single page

Redirect 301 /oldpage.html http://www.yoursite.com/newpage.html
Redirect 301 /oldpage2.html http://www.yoursite.com/folder/

Redirect an entire site

This way does it with links intact. That is www.oldsite.com/some/crazy/link.html will become www.newsite.com/some/crazy/link.html. This is extremely helpful when you are just "moving" a site to a new domain. Place this on the OLD site:

Redirect 301 / http://newsite.com/

	     url('webfont.woff') format('woff'), /* Modern Browsers */
	     url('webfont.ttf')  format('truetype'), /* Safari, Android, iOS */
	     url('webfont.svg#svgFontName') format('svg'); /* Legacy iOS */
	}

body {
       font-family: 'MyFontFamily', Fallback, sans-serif;

Tutorial Two-Color Three-Dimensional Blocks and Text

by in , 0

We can use multiple text-shadow and box-shadow values to create a three-dimensional look to blocks or text, like this screenshot of David DeSandro's footer. However in that example, the "three dimesional" part is a solid color.

By alternating colors back and forth in the "stacking order" of our box or text shadow declaration, we can simulate a more three dimensional / lighted effect.

text-shadow:   1px 0px #eee, 0px 1px #ccc,
               2px 1px #eee, 1px 2px #ccc,
               3px 2px #eee, 2px 3px #ccc,
               4px 3px #eee, 3px 4px #ccc,
               5px 4px #eee, 4px 5px #ccc,
               6px 5px #eee, 5px 6px #ccc,
               7px 6px #eee, 6px 7px #ccc,
               8px 7px #eee, 7px 8px #ccc,
               8px 8px #eee;
