Today started celebrating ColdFusion month with series of 30 blog posts on ColdFusion 10's new feature and here first one. This is really not a new feature or enhancement but new administrator setting which may give 400 error (it's not 404) project already running in older version of ColdFusion. In administrator new setting available "Maximum number of POST request parameter" which is default set to 100 means you can post maximum 100 parameter to ColdFusion on form submit. Normally 100 parameters are sufficient for any webpage but in may case I have very complex search which numerous search parameters which exceed ColdFusion administrator limit and when try to submit page give 400 ColdFusion error at first glance confuse with 404 error (seems Adobe change default error template). Even though I have onError method in Application.cfc to catch any ColdFusion error but seems this stopped at server level before executing my Application.cfc. To make sure page exists I had directly paste URL in browser and seems work fine and it drive me crazy, why it showing error while submitting the page????

We all know ColdFusion 10 is out and lots of tweet regarding release. As usual my first step was to install ColdFusion 10 in my dev computer and going everything smooth and start testing ColdFusion 10 with my existing projects which were running under CF9 before. Seems everything working good so Adobe take care of backward compatibility, I have a project on development computer since CF7 era and this project migrated to CF8, CF9 as new ColdFusion version released. When we move from CF8 to CF9 was really tedious job for us because of ExtJs version changed. 

Found list of new features in ColdFusion by Charlie Arehart and decided to checkout all new features (atleast one per day) and blog that. Below is list of all 30 days series for ColdFusion 10. (I will add link as post available on that day :) )
