Building a website is a complicated process, and testing your finished product on every possible browser can be even more daunting. However, because modern browsers such as Safari, Mozilla, and Internet Explorer 6 are compliant with the World Wide Web Consortium's (W3C) standards, testing your pages with the W3C Validation Tool is a great way to ensure that your pages work with modern browsers. The W3C Validator provides a line-by-line level of feedback, such as error information with references to the standards, on any URL you submit or HTML file you upload. But what if your pages are accessible only within your firewall? Or what if your organization is reluctant to have their pages submitted to any external site for validation—even if it's fully automated? This article describes how you can host the same W3C standards validation service within the confines of your own network and security constraints. You just need to download a number of open-source components that are freely available, and then configure them properly. By following this recipe, you will have an internal validation tool that will not only be accessible to your web developers as needed, but can actually be integrated into your production process. You have the code—you can make it fit your workflow.
