Re: [ACFUG Discuss] cfcontent in IE7

[Dean H. Saxe]

Correct Charlie, but in this case it would be helpful to ensure you  
always get fresh content until everything starts working.  You can  
alternatively use a MITM proxy like Paros to ensure all caching  
headers are ignored, thereby pulling fresh content all the time too.

caching

the old bad page (or just some aspect of it).

Try closing the browser and reopening it (or even just browsing the

There could be other issues, of course. I've not considered your code
carefully. This is just such a common problem and easy first solution

[ACFUG Discuss] Session variables

[Fennell, Mark P.]

Greetings,
Is is possible to use J2EE session variables in one CFApplication and
standard session variables in another? 
I have a server that is running two cfapplications and one uses J2EE
variables and seems to not work so well when J2EE Sess Vars is disabled
in cf admin. The other applications totally breaks if I have J2EE
enabled. I was hoping that, before I set about actually fixing the
problem with code that there might be some setting in the cfapplication
tag that I can use to enable/disable j2ee vars for a specific
application... I'm completely prepared to recode, I just wanted to check
and see if anyone had an easy way out. Thanks.

RE: [ACFUG Discuss] Session variables

[Fennell, Mark P.]

Yes, it is odd that the change would break something. 
I'm using lylaCaptcha and when I enable the J2ee session vars it stops
generating the image. I'm going to dig through the cfc and see if it
relies on something specifically anti-j2ee. But that doesn't make sesnse
as it uses java to create the image. Weirdness. Wishing I had CF8.
Thanks.

You can't have it both ways on the same server instance.

For the one that breaks when you have it on, are you doing things with

Re: [ACFUG Discuss] Session variables

[Cameron Childress]

I'm unclear on what impact CFLOCK had on this, but as a side note, you
can actually trim up that code quite a bit.  I frequently see people
using CFOUTPUT and pound signs where they aren't actually needed, and
this is one of those cases.  It may seem a little petty to point this
out, but it can really clean up your code and make it more readable,
not to mention taking less keystrokes to write code.  Really all
that's needed here is:




CFOUTPUT is only required when you are outputting code to the screen,
and the pound signs are only needed in cases you are instructing the
compiler that you are using a variable instead of a literal string.
In this case, since it's in a CFSET tag you don't need the pound
signs.

RE: [ACFUG Discuss] Session variables

[Charlie Arehart]

Just to clarify, this isn't something you can do at the application level in
CF8. I was under the impression myself for a while that we could do pretty
much everything at the app level now, but it's just mappings and custom tag
paths. Perhaps in a later release. :-)
 
So, no, the J2EE sessions mechanism is a one for all and all for one sort of
thing (unless of course one runs on Enterprise and creates another
instance).

RE: [ACFUG Discuss] Session variables

[axunderwood]

There are SOME situations where they can be a problem..if you have a single 
sign on type of interface for several applications and users can open new 
browser windows and *expect* to be able to go directly to another one of their 
secured apps, the sessions won't exist in the new browser and may cause 
problems.  I'm sure there are workarounds, but I thought I'd throw that out 
there.  The J2EE sessions are browser specific so opening a fresh browser will 
essentially disassociate the CF session with the new browser window.

Re: [ACFUG Discuss] Session variables

[Dean H. Saxe]

Uh... that's a browser implementation not a problem with CF or the  
state maintenance mechanism.  Specifically, MSIE can open windows in  
different processes, when this happens the memory resident cookies  
(session cookies) do not get shared between browser instances.  This  
is configurable on Windows boxes.

The reason this doesn't happen with CF cookies out of the box is that  
they are not session cookies, therefore they are persisted to disk,  
accessible to all MSIE processes.

RE: [ACFUG Discuss] Session variables

[Charlie Arehart]

Shawn, I started to offer some of that info but thought twice (some say my
emails are too long) so I removed it. So since you're asking...:-)
 
If folks don't mind I'd rather point to some blog entries I did back in 2002
where I discussed the pros and cons of the J2EE sessions. I know you're
asking why anyone would stick with the old form, but really, others may
equally ask why they should switch to the new. Or they may have tried and
had problems (which does go to your question)
 
In the entries, I explain the differences and even at least one gotcha
(relatively rare) in using them that I don't think has been resolved.

well: http://coldfusion.sys-con.com/read/41646_f.htm. 
Just haven't reviewed that info for a while to see if the article and comments 
or the blog entries have all the same info, or which would be more 
authoritative 
of what I'd observed.)

 

Hope 
it's helpful.

I guess I 
don't know why anyone would use the old session variables anymore. I always use 
the J2EE session variables instead. Maybe someone can enlighten me to the any 
benefits or trade-offs of either choice.

Just to clarify, this isn't something you can do at the 
application level in CF8. I was under the impression myself for a while that we 
could do pretty much everything at the app level now, but it's just mappings 
and 
custom tag paths. Perhaps in a later release. :-)

 

So, 
no, the J2EE sessions mechanism is a one for all and all for one sort of thing 
(unless of course one runs on Enterprise and creates another instance).

RE: [ACFUG Discuss] cfcontent in IE7

[Charlie Arehart]

For the benefit of the viewing audience :-),  can you clarify what it was
that "worked" for you, Troy? 

It seems you're referring to Dean's last note, and that may be what you
meant. I'm just curious (for instance, did simply browing the page in a new
window not work for you)?
