On 4/25/07, james carberry wrote: What is the best way to store client variables? Better way to phrase that is what is the least bad way? :-) Cookies are a disaster. To make a long story short you can't count on them being present all the time, and you have to wait for a trip to the client and back before you can use one thats been set (unless that behavior has changed over the years). Plus they can be hacked ore easily, being client-side. All of the true nightmares I have experienced with cvars have been when I discovered the site owner was storing them in cookies. Writing to the registry... It works, but horrific consequences possible if a write goes bad. Other nasties possible. For example your site gets hit by an ill-behaved bot two zillion times and it creates two zillion entries... in your registry. Your now-uber-bloated registry. 'nuff said. Writing to the db. As robust as your db is. Nobody loves a thing that executes a db read and write at every page request, but at least there are no vultures circling your server when you do it this way. The problems you will cause will be manageable, one way or the other. Lest you think I hate cvars, I do not. I still use them at least to some degree, although mostly in legacy apps. I try to rely on session vars. -- [EMAIL PROTECTED] Janitor, The Robertson Team mysecretbase.com ~| Upgrade to Adobe ColdFusion MX7 The most significant release in over 10 years.

Re: Preferred clientstorage setting for client variables
dont forget that these days people have their browsers configured to remember stuff for them, so they may not need a cookie to do that - Original Message From: james carberry [EMAIL PROTECTED] To: CF-Talk cf-talk@houseoffusion.com Sent: Wednesday, April 25, 2007 2:58:06 PM Subject: Preferred clientstorage setting for client variables What is the best way to store client variables?

Writing to the db. As robust as your db is. Nobody loves a thing that executes a db read and write at every page request, but at least there are no vultures circling your server when you do it this way. The problems you will cause will be manageable, one way or the other. Unless you need to track the system-generated Client variables (hitcount, lastvisit), you can avoid an update for each page that doesn't otherwise change Client variables by disabling the appropriate option in the CF Administrator.

RE: Preferred clientstorage setting for client variables
What is the best way to store client variables? We are in the process of completely redesigning our website and considering changing the clientstorage attribute in cfapplication from a named SQL datasource to Cookie to prevent having 100,000's of records pile up on our SQL server. The primary use of this would really just be to allow the user to have their login status remembered so they would not have to log into our site every time. Any arguments one way or the other? I would generally recommend the use of database storage, if you have a reliable database. SQL Server is certainly reliable enough for this. Just make sure you purge records as appropriate, and disable global client variable updates if they're not needed. There are several problems with using cookies to store any significant data: you don't have any control over them, they can become large and unwieldy over time, they may get lost or truncated for unexpected reasons.
