OK got a strange one. I think this will end up being an NT permissions
problem but thought one of you may have come across it.
I have a web site which sits on 2 seperate web servers. It is load balanced
and state is maintained via client variables stored in SQL server on a 3rd
machine. All 3 are networked. I have a cfm page on both web servers which
is attempting to create a file on the 3rd machine using cffile. Both web
servers have mapped drives to a folder on the 3rd server so when this cfm
page is requested it writes a file to the same place regardless of which web
server delivered the page (due to load balancing).
The problem I am having is that when CFServer executes the cffile command it
says that it can't access the file. I have checked all the permissions on
the NT server and that folder is opened up for full access to everyone. I
have tried sucessfully to create a file in this folder from a dosbox on one
of the webservers so the path I'm using is definitely correct. To
complicate the problem I have changed the code to write to C:\ (which exists
on both web servers) as opposed to the mapped drive to the 3rd server. This
works fine. However I can't use this as I won't know which C drive it has
created the file on due to the load balancing and when request the next page
which looks for this file it will not find it if the page gets delivered
from the other web server.
Finally I put a specific IP address in the url that requests the page that
creates the file and subsequently reads it so I could guarantee that it
would write and read to the same server (ie bypass load balancing). But
when I did this the session auomaically expired (which I don't understand).
Has anyone ever come across anything remotely similar to this by any remote
chance!???
