jQuery Ajax and Passing Data

I was having an issue the other day with passing an ampersand into a script via jQuery Ajax. 

I was doing this: data:"category="+category+"&groupname="+groupname, If the groupname had an ampersand in it the variable was getting cut off. After do some research on the issue I found a better way to pass in data. This improved way of passing in the data automatically url encodes the data to be passed in properly.


Chrome extensions I use on a regular basis

Google Chrome Sync feature makes it easy for me to remember what extensions I use because if I reinstall and  re-enter my account credentials it will reinstall the extensions for me.  It is a pretty cool feature.

Remember to restart Railo / Tomcat   afterwards:

/etc/rc.d/init.d/railo_ctl restart

The part I have been struggling with for so long was how to do password protected directories in apache.  Either by adding the config to the VirtualHost directive or by .htaccess.

It seemed no matter what I did, requests were getting proxied and there was nothing I could do about it.

Tonight I finally found my answer:

ColdFusion By Example - Comparing strings

After a slow start I finally completed the first post of my Coldfusion By Example series.  I am not extremely happy with it yet, but I need to start somewhere.  I feel like I did not add enough explanation to the post. There is not much to say about comparing strings.  I will review the post again in a couple days and see if I can add any more to it.  I am also open to any suggestions.
