Web Site Pre-Flight

When taking a site live onto a production server, it's always tempting to rush the last few steps, especially if you're under a launch deadline, or if you've been working on the same site so long that you're sick of it. At this point it's important to sit back, take a breath, and be sure to go through the following pre-flight checklist:

1. Check for broken links
2. Disable any debugging lines in your code
3. For PHP-based sites, set error_reporting to NONE. Errors should be redirected to a log file.
4. Remove any insecure files like phpinfo.php
5. Be sure your .htaccess file contains the Options -Indexes directive
6. Validate your markup, css and accessibility standards
7. Check for broken links again.

• User Agent Switcher: Allows Firefox to forge http response headers and pose as IE or another browser
• Pinger: Check for broken links on a page
