The excrutiating detail of the Citrix logon process: A huge wall chart

Kevin Goodman and I spent some time together last month and put together this huge, poster-sized, very detailed chart that details the entire Citrix logon process. It was for a session that we gave at BriForum a few weeks ago. And of course, now that we're done, we're releasing it for free!

Click on this image to download the medium resolution JPG version

You can get this thing right now be clicking the links at the top of the article. The 150dpi version should be good enough for you to view on your screen. The 300dpi version is good enough to print out.

In case you don't have a spare poster printer at your disposal, we made this poster available via our Cafe Press store. You can order it online for $20 and you'll receive it in a few days. (It's about 2 feet x 3 feet in size!)

So print this out and stick it on your cubie wall. That way when your clueless boss comes by and tells you that logons are slow, you can just say (pointing to the wall), "Sure! Just let me know which part and I'll get right on that!"

I'm sure that we'll find errors in this, and there are some parts that we want to flesh out, but overall this is pretty solid.

Hey Brian,

Like I said to you and Kevin and BriForum. The chart is absolutely of the chart!
It's gotten endless effort written all over it. I think you guys did an absolutely great job.

Okay, as of about 2:08PM (19:00GMT) today, I have made a few changes and posted a new version, so go ahead and grab it again. I've also updated the one at Cafe Press.

The first box says "Users Double Click"...  I don't know about the rest of you, but when a user double clicks to launch an application....two applications launch.  Web Interface is a "Single Click" to launch applications.  I use the HideApp mod for WI to prevent double clicking.

Hey.. I did say that the "user" double-clicks, right? 

Actually, there's that setting in the ICA file that sets a timer that ensures plenty of time passes before the client makes a new request, so double-clicking shouldn't lead to two sessions. However, your point is right on, and I'm adding that to my list for the next version of this chart.

Thanks,
Brian

this chart is absolutely awesome. Could you please post a PDF version of it? I like to print it quite large in the best possible quality ...

Thanks!!!

Regarding the PDF version, the 300dpi JPG is better quality than the PDF. The PDF had all sorts of problems with so many layers, and the shading didn't look right, and it was slow and huge.
 
The 300dpi JPEG is what we printed for the posters at BriForum, and it looks great.

Hi. Quick question - which setting in which ICA file sets this timer? I've looked at SucConnTimeout, but that made no difference to our problem with users double clicking the WI icons. I added it into the WI default.ica in the section.

Thanks,

Nick

Open the 300dpi jpeg with MS Paint and set margins to the smallest your printer will handle.  Now do a print preview; the printout should take 10 or 15 pages.  This will let you trim up the edges and tape them together (just did it, looks good).

Ugh, even the 150 dpi creates a 171 MB print-job and the result is practically "un-readable", as far as my experience goes. Mspaint loads the .jpg and then just dissappears to nowhere. Photo-Editor say, it's too many bytes. Trying to print from MSIE (5.5...) on a A3 printer procduces empty pages. Ugh. Isn't there a way to make a less fancy version of this, say black and white with emphasis on words rather than appearance ?-)

Hi Brain,

I had gone through the excellent Logon process defined by you @ http://www.brianmadden.com/content/content.asp?id=587.
 
I have some questions.Please clarify.
 
1.In the server selection section, you have pointed two circles indicating end of process, if that is the end of whole proceess then when they will go through client connection,microsoft licensing validation,session initialisation printer mapping.
 
Please clarify.

Any time you see a circle that is an "end," then yes, that's the end of the whole process. If you end by reconnecting to a disconnected session, then you will not go through the printer mapping process again.

Hi Kevin
Hi Brian,

thank you for your detailed chart which is very usefull.

From a developers perspective I have a specific question about "Icast.exe".

In your chart you wrote the comment "Icast.exe (ICA Application Laucher) waits for wfshell.exe to finish first before launching the initial program for published app".

Is it so that "Icast.exe" is waiting for the termination of the published app to clean up the session afterwards? Or will "Icast.exe" terminate after it has successfully started the published app? I am just trying to figure out which process stays in memory on the citrix server when published applications are started.

Thank you for clarifying this detail,
Holger

Is there an updated version of this chart for XenApp 5 or is the process the same?
