When using the cfinvoke tag or the CreateObject function on your pages, it adds CPU time to process the requests to load all of those objects into memory. Under load this can make quite a difference in your page response times. One way to get around it is to put those objects into a shared scope so they only get instantiated once. This will save memory and CPU time on your server.

Ever wanted to do something a little more than what ColdFusion was capable of doing? Kind of a broad question right? What about scan files for viruses? Spell check form fields?

Well that is not exactly true, but you can use ColdFusion to get your OS (operating system) to do whatever you want.

This tutorial explains how to do simple urls like: http://www.domain.com/username Or http://www.domain.com/page_name.
It is different from doing Search Engine Friendly urls (like http://tutorial90.easycfm.com/) because this doesnt convert urls.
In a way it unconverts a url by taking advantage of a 404 missing page.

Internet spam is on the rise, and more importantly spammers are targeting your sites comment forms. They are looking for the trackback urls to fool search engines into ranking their website higher in the search results. When this started to happen to me, I wanted to sent out emails to the offenders demanding that they stop. Unfortunatly the spam is being generated by bots and programs not some pimple faced kid behind a keyboard. Banning IP addresses is not enough and rarely works since intelligent spammers hide their true identity anyway. Next approach... Banning Keywords used by the offending sites. Thats where this tutorial comes in.
