Re: ISAPI filters

[Andrew Clarke]

I don't think these will be issues in this instance.  I also meant to try using 
the wildcard dll specifically for .cfm requests instead of cf-iis6.dll or 
whatever, but now that I'm thinking about it I'm not sure if I actually did 
that.

I did try without the wildcard.  That allowed .HTML files to work but .cfm 
still didn't work.

Re: ISAPI filters

[Andrew Clarke]

Thanks all of you for your suggestions.  I'm actually camping and off-roading 
this weekend, but here I am by the campfire, iPad lovingly nestled on my lap, 
because I appreciate everyones' responses, haha.

Unfortunately this environment isn't easily open to switching around to a 
reverse proxy although it's something to bring up.  The setup was working with 
CF 7 and it probably took me 15 hours to set up their staging servers as I spun 
my wheels for a while unsuccessfully trying to run wsconfig and having other 
issues.  When I finally cracked that problem I thought production would go 
better.

I worked on it from 20:00-05:00 the other night, including the time to roll 
back to the previous config, which fortunately still worked,

Staging and production are of course supposed to be identical but in this case 
apparently they aren't.

Thanks Dave for explaining that the wildcard filter will intercept all 
requests.  I thought that extensions set up as MIME types in IIS were handled 
natively and not passed through.

Well, the change was aborted, and now meetings must commence to decide what to 
do about it.  There was another CF instance that had to be upgraded due to an 
incompatibility introduced by a vendor and at least that one went without a 
hitch.

Andrew.

Hi list,
a customer of mine ran a CF-shop
on a windows host with IIS.
Now he has a new PHP-Shop running on
another host with apache.
Anyone here who can describe how
I can write a ReWriteRule on the
apache server based on an .htaccess-file
that requests to: www.xyz.com/shop.cfm
are being redirected on the new
host to: www.xyz.com ?

This makes sense to me.

How would the AJAX client know anything about CF mappings? CF mappings
only mean something within CF code. Once you're in the client, you
need URLs that the client can understand.

logout and back button

[Richard White]

hi,

i am storing user data in the session scope. when the user logs out it runs a 
structclear(session) and a cflocation back to the login page. 

in the application.cfc onrequeststart function it checks if the user 
information exists in the session and if not runs a cflocation back to the 
login page. 

however after logging out, i am able to click the back button and get back into 
the last page in the software.

i have read a few posts about this situation but havent found a suitable 
solution yet, how do you guys handle this situation?

thanks

Re: Coldfusion 8 vs 9 - cfc mapping differences?

I am also experiencing the same problem.
When I use a cfajaxproxy, per application mappings set in Application.cfc
are not picked up. I have to use a fully qualified path from the web root
inside the proxied cfc.

That will fix this problem, but it will introduce other problems. CF
does rely on URL patterns that don't necessarily correspond with
extensions or physical locations that exist (CFIMAGE, RDS, etc) and
those rely on the use of a filter rather than an extension handler.

Coldfusion 8 vs 9 - cfc mapping differences?

[John Pullam]

I'm struggling a bit with running some previously operational applications 
under CF9. It seems that most of my challenge comes from cfc invocation. I've 
been browsing around trying to understand what has changed but haven't come up 
with anything much.

I have my cfc's in the same folder as my normal templates. So I would expect 
that the following code would be valid because BSelects is in the same folder 
and getSessions is in the cfc. This worked in CF8. Is there something new I'm 
missing? 



CF says that the cfc BSelects could not be found. This should be simple but I 
don't get it!

 Instead of using the isapi as a wildcard, try having it be the handler for
