And your operation fails. You're then prompted to "Click here to login", but even if you back up or client another link, you'll be prompted with the CF Admin login.

What gives? Why is it happening? And how can you fix things? Is CF broken? No, not in the sense that you need to reinstall or anything. The good news is that there is a quite simple solution. Well, there are several, depending on your goals.

The simple solution: delete the duplicate cfid/cftoken or jsessionid cookies that you will find your browser is sending to CF. But there is much more to this, as well as other solutions, which would be worth most readers taking a few minutes to read on here.

BTW, the same root problem can be the cause of your own application's users finding that they can't stay logged in. More on that in a moment.

I don't hold that out as a real possibility, for a couple of reasons, and I'd like to discuss them here.

Indeed, it's a good time to share a "State of the Online ColdFusion Meetup", to discuss what you might (and might not) expect to see in the future, and what you can perhaps do to help.

I'm holding a glimmer of hope that it's all an April Fool's prank, but if true it's indeed the end of an era and time to pause and reflect as if on the passing of a friend.

Update: I'm vindicated! :-) The guys announced in their next show that it WAS INDEED an April Fool's prank. Even so, I'll leave this entry, untouched, for posterity. Plus, most of the info is just as valuable to have shared, with them and with readers, whether they did or did not end the show. And like I said below, this gave them a chance like Twain and Nobel to see what folks thought when they thought they were dead. :-)

I also want to give some solace to fans of the show (and the general CFML community) with respect to where they may want to turn now to keep up on news, resources, etc. Fortunately, there are some places being actively updated. (And while surely some will see this as one more nail in CF's coffin, I don't and I'll address that briefly too.)

But first let's give credit where it's due about the podcast...

Of course, in CF10 it's easier now because of the built-in "server updates" feature of the CF Admin. But in earlier releases, it was all on you to both keep up on the updates and to apply them manually. And a lot of people either never bothered, or may have tried and failed, or did it but got it wrong.

What you need to know

So in this blog entry, I some key info that will help you, if you may be in need of applying one or more of those updates to CF9 and earlier. Indeed, I'll point to some past entries I've done where I shared a lot more detail that I find is vital and rarely mentioned when some people try to share just the bare minimum of info (often leaving people hanging).

For instance, I'll help you answer such questions as what hotfixes do you already have applied? How do you find out? And you need to know exactly what version of CF you have, whether 9.0/9.0.1/9.0.2, 8.0/8.0.1, 7.0/7.0.1/7.0.2, and so on. I'll explain how to tell and why that's important, and especially when it comes to finding and applying hotfixes. And if you have applied hotfixes, are you sure you have done it right? It's easy to get things wrong and botch things. I'll help you avoid several very common mistakes.

(That's why it's so great that CF10 finally handles things for us. But this entry, focused on 9 and earlier, is not the place to discuss concerns with the CF10 hotfix mechanism. If you have questions or concerns about that, see the substantial CF10 Hotfix Installation Guide from Adobe, a 50-question FAQ on all things related to that feature.)

I'll also point you to where to find hotfixes and installers for CF9 and earlier (not as easy as it may seem), and still more.

If any of that's of interest, and I hope it is if you're on CF9 or earlier, then read on.

But guess what: it technically only has changes related to Mac OS X (specifically adding support for its Mavericks version).

This is addressed if you read the technote that the update text points to, or the Adobe blog entry from last night which announced the update (more on these in a moment.) Those DO indicate that if you are not running that OS, you need not apply the update. (And the day after I wrote this entry, this indication was added to the update text itself.)

But what if you are on Windows (or another *nix variant besides OS X)? Should you apply it? What if you do? (there's NO PROBLEM!) What if you don't? And given that the update text says you need to reconfigure the web server connector, do you really need to bother on Windows?

And what if you are installing CF10 for the first time, since you DO need to apply updates upon installation? (you can either apply update 13 or 12, but you must apply at least one of them to be fully updated.)

As important, how might Adobe have better clarified this, and how might they make a simple change now related to that (they since did)?

I address in this entry these questions and a few other concerns I have, about confusion that may ensue.

They don't run in the background, only doing their job when you ask them to, so I find them safe to install and use on production servers, though of course any tool can be abused. I've never seen these to cause a problem in many thousands of uses.

I was reminded to share this list today as I was helping a customer, as I got on their server with them to help them solve a problem. I recommended we install these as I do on nearly all my engagements (and indeed on all my own machines). I think they really are fundamental tools, as I'll explain below.

First video, on single-login problems in CF10 Admin

The first video was done at cf.Objective() in May 2013, and was posted to YouTube by Adobe shortly thereafter:

Video 1: Solving the problem of single-login in ColdFusion10 (07m:32s)

If you've had the problem in CF10 of finding that you login to the Admin, only to be logged off soon thereafter, I explain in the video both why it happens and how to solve it. (I also wrote about it previously here.)

Second video, on important security hotfix notes document

The second video was done back in June, but sadly was not posted until last week. While the timeframe references I make are dated, the information shared is not and really may still be a surprise to as many now as back then:

Video 2: Security Hotfix Notes Document (5m46s)

This is such an important document. I also had written about it previously here.

See other CF videos there

Be sure to check out all the videos in the Adobe CF YouTube channel, about 20 of them currently, from different speakers and on many topics.

I wanted to point out to my readers that I have proposed two talks. The first one I gave at the Adobe CF summit last month and was very well-received. You can see the description and VOTE button on each of the following pages:

CF911: Solving Frequent CF Server Problems in New/Better Ways (click to visit, then vote)

The second is one that I gave to the Atlanta CFUG earlier this year.

Updating/Hotfixing ColdFusion 10, 9 and 8: Tips and Traps (click to visit, then vote)

Both are full of surprising and helpful tips, based on my experience helping hundreds of shops with related issues in my CF server troubleshooting services. But the talks are not "sales pitches".

They're goal is to be just like my blog entries here, and my past talks: I just want to help people find, understand, and resolve problems with their CF servers. It's wonderful to be able to help people come away more confident and capable in managing their servers, whether from the consulting sessions, the talks, the blog entries, the cf911.com wiki of cf server troubleshooting resources, the cf411.com site of tools and resources of interest to CFers, and so on.

Anyway, if these talks sound interesting, please go add your votes using the link for each above, and click the vote option that then appears. And of course, vote for all the other talks you think ought to be invited. The board uses your votes, so every vote counts.
