Re: CF session management suddenly not sticking ...
I think it was pretty clear that code he listed was being used solely to diagnose a problem he was experiencing **on a production server** and from **multiple client computers**, and that wasn't necessarily reproducible on a development server. And I don't think the code was meant for permanent use. So I think your assumptions and gruffness and were a bit off the mark. -Carl V.

Re: CF session management suddenly not sticking ...
Opening a private browser window will always solve the problem. With that in mind, whats the best way to reset cookies on session start? I am using application.cfm. What could cause this? Underlying CF code from the current site has barely changed. The problem, I think, is related to changes in session management in recent releases of CF to prevent session fixation vulnerabilities, etc. You might have CFID/CFTOKEN cookies that have different domain attributes, and CF is looking at the wrong ones, if I recall correctly. Here's a workflow description from a guy who's smarter than me: - go to a site that uses restricted cookies: - a cookie gets created (e.g. only valid for the path /admin); - visit a page on the same domain, but outside the restriction: - browser doesn't send cookie; - a new cookie gets created (valid for /); - go back to the restricted area: - browser sends both cookies. The best solution, in my opinion, is to switch to J2EE sessions, assuming you can invest the time and effort to do that.

Re: what is faster?
cfif(serializeJSON(qry1) eq serializeJSON(qry2)) to compare 2 queries or sticking the queries into an array and then cfif #qryArray1.equals(qryArray2)# IS YES As several people have described here, you can test this (serially) yourself very easily. But on another note, I really hate these which is faster questions, because (a) the differences are usually trivial, (b) the way most people measure these things is misleading, and (c) there often is no actual right answer. First: assuming that you have a finite amount of time - I think that's a safe assumption - you would be far better served optimizing your SQL and your asynchronous processing. I've been working with CF for many years, and I've looked at a lot of applications, and it's very rare that I find one that has really been fully optimized in those two respects. Those are going to get you a lot more bang for your buck, so to speak. Second: measuring something serially doesn't mean that those measurements will also apply to parallel operations. In other words, what runs faster with one user doesn't necessarily run faster with ten users. You really need to test things concurrently to get a useful measure, and running concurrent tests is time-consuming and expensive, so you really only want to do it when there's a useful payoff. Third: let's say you test this today, in parallel, and find out that one is faster than the other on your version of CF. Will that hold for other versions? I can't count the number of times that I've found legacy code that worked well in one version of CF, but no longer works well in another version. In summary, I recommend you just choose the simplest approach - in this case, the first one - because it will be easy to understand and will work adequately well.

Re: CF session management suddenly not sticking ...
I think it was pretty clear that code he listed was being used solely to diagnose a problem Precisely. Its the production environment but not the production site. I'm testing with some old in-office desktops that mimic the problem reported to us by users when this site was live for roughly 24 hrs before I pulled it. The best solution, in my opinion, is to switch to J2EE sessions, assuming you can invest the time and effort to do that. Seeing as my efforts on this seem to be going nowhere (old browsers will occasionally start working but always revert after a TBD period of inactivity) that sounds like good advice. Working on that now. And its all happening on a CF-based site that has been humming along in its present form since 2006... all we did was make it prettier... re-skinned it with a different front end. And it still works fine for the majority of visitors. Any chance you are using Chrome in Incognito mode? Nope. The only place I can replicate the issue is on IE8 running on XP. Or maybe you have an add on that is killing cookies. That was my very first thought and I went straight to the design team who swore that we weren't doing anything genuinely different. Nonetheless we pulled a bunch of stuff out with no success. To finally clear that I wrote up the bare bones page (previous post) and it too is evidencing the problem.

Those are going to get you a lot more bang for your buck, so to speak. +a lot Most of the CF applications I've worked on in my career haven't been run under real load or scale of any kind (lots of back-office stuff and smaller websites) and I've found that in many cases the which is faster doesn't matter in most cases anymore. It mattered a little bit back in CF4 when the server was a single 500Mhz Pentium III, but with modern versions of CF on modern hardware, the differences are negligible. (Sure there are cases where the CF code is just gross and is impacting performance, but that's a far cry from nitpicking whether expressions should include pound signs or not or if you should have one large cfoutput block or wrap each expression independently like some used to bicker about back in 1999). In the past couple of years I've been working on larger public-facing applications that do run at scale, and have found that the database tends to end up being the bottleneck. Learning about the internals of your database engine and optimizing your data structure, indexes, how execution plans are generated and cached, tuning the queries themselves, and so on has had far more impact on performance than anything in the CF code. -Justin ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:357889 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

Amongst the many things I do I also collect classic computers.

You click on a little icon on the image at Getty Images and it gives you a bit of iframe code like the example below. iframe src=//embed.gettyimages.com/embed/123395871?et=hq0KB-XOg0yifXKaQ3Bj0wsig=4 a9zo-buxXQxavnQaAM3LqOQME9VyhjHlwWZl_KOZP4= width=400 height=585 frameborder=0 scrolling=no/iframe My question is whether it is possible (or even if there is any need) to check that this code snippet actually returns something when its loaded so that you can handle it on the page e.g. Getty Images down, image removed from their collection etc. Thank you ++ Kevin Parker ++ ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:357894 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
