<p>I'm trying to setup an alert to let me know via email (SMTP) when free disk space on one of my servers is less than a specified value. To do this I'm using PerfMon alerts, as described at <a href="http://support.microsoft.com/kb/324796" rel="nofollow noreferrer">MSFT Technet</a>. I have the alert working and writing to the system log, but when I try to set it to 'Run Program' it fails. The log alert fires but the program fails.</p>

<p>The program I'm using is a small C# app I wrote to send an smtp email. I have tested the app independently from this server, running it manually and it works fine, without any user interaction (console app). But when I have it set to run via the alert trigger it fails.</p>

Yes, I believe it is caching. I see this behaviour on Firefox for example (not Safari, for what that's worth :) ).
you can reload the page and bypass the cache (on Firefox) using
CTRL
-
SHIFT
-
R
and you'll see the check value doesn't carry (a normal
CTRL
-
R
will grab the info from the cache however)
edit
: I was able to disable this server side on Firefox, setting a cache control header:
```
```
Cache-Control: no-store
```
```
this seems to disable the "remember form values" feature of Firefox
