Dear readers, if you haven’t checked out the SEO Toolkit yet, you owe it to yourself to go there now, download it and start using it. Point it to your sites and it will explore them and give you a full report of all the little problems that are getting in the way of search engines.
I would be very grateful if you could drop me a note in comments answering the following questions:
I've blogged in the past about injection attacks. Microsoft publishes additional new tools to detect and protect against injection attacks. The first tool, developed by HP, crawls web sites to automatically detect possible attacks, the second blocks dangerous requests from being executed, and the last one analyzes code to look for dangerous practice.
Mike Volodarsky wrote a fantastic article in the January 2008 issue of MSDN magazine in which he explains how you can take an existing PHP application (he uses QDig, a popular image gallery) and improve it without touching a line of its code. This is a great demonstration of the power of IIS 7's modular and pluggable architecture. Mike was able to add the following features to this PHP application using only managed code modules and configuration:
- Access control using the ASP.NET membership APIs.
- Forms authentication.
- Pretty URLs (http://myphpgallery/index.php/Mike/Flower.jpg instead of the default http://myphpgallery/index.php?Qwd=./Mike&Qif=Flower.jpg) and rewriting of all URLs that are generated by the application to be pretty.
- Output caching (which is a feature Zend charges for but that comes with IIS), leading to a whopping >15x improvement in throughput over the already performant FastCGI.
It really is amazing that you can add such complex features to an existing web application without touching its code. It is also super-simple to do. It looks very much like aspect-oriented programming if you think about it, only it's easy to set-up and understand.
The only thing I'd have liked to see and that isn't in the article is a comparison between the performance of the application on a LAMP setting with Zend's platform configured and the performance of the same application with Mike's improvements on IIS.
