Re: Tomcat 4 problem?--Graphics randomly fail to load

[Scott Judd]

Hi Andy,

Thanks so much for the input. My server is running on Win2k Server, so I'll
certainly research the connector issue; however since I'm running Tomcat as
a stand-alone, I'm not using mod_webapp. OTOH, it will save me a lot of time
not to bother with configuring a tomcat-on-apache server to see what
happens.

We have seen the same problem on windows too. It happens randomly. I think it is a 
problem with the HTTP connector.

My files set the NO-CACHE meta tag, and my browser prefs are configured to
always request new information (i.e., no caching of files). The problem is
still present.

What happens if you tell the browser to not cache images at all, i.e.
always go back to the server?

Scott,

If your server is running on Windows, I believe this is a common connector
issue.  It certainly happens to me with mod_webapp.  It doesn't happen on
the production Linux server though, so it's not an issue for me.
