Subject: Re: Tomcat Jakarta 1.2.31 ISAPI Reconnector incorrectly
sending Content body with HTTP 304 Status
10054 is a winsock error code, so
A lively debate will no doubt follow, if the HTTP and Servlet specs
differ, but I don't believe a modification type header is appropriate
for a 404.
So that, I suspect, is a bug. You can add it to bugzilla unless this
email is followed by people pointing out that I'm completely wrong.

Many thanks for fixing the bug.
I would like to add that the HTTP 304 responses were all generated by
accessing static resources in a Tomcat webapp (images, css files etc), not
by accessing some servlet or JSP. I don't know why there was sometimes a

Rainer,
Thanks very much for the help. I can't believe I didn't catch that!
Works fine now. For what it's worth, the linux server obj.conf file did
not have that goofy 3= stuff, it just had the Service command on the
same line and that was enough to break it.
Thanks again!

Hi Matt,
I tried with SJSWS 6 sp11 on Solaris 8 together with nsapi redirector
1.2.25. I could reproduce the problem, and I could fix it with a small
variation of your configuration, which seems syntactically invalid:
Your original configuration:
Object name=jboss
ObjectType
Hi everyone,
I'm having a rather strange problem with the nsapi_connector for Sun One
Web Server 6.1 connecting via ajp/13 to a JBoss application server.
Basically, if the JBoss server returns a HTTP code 304 for a browser
cache hit, the SWS is instead looking for the file in its own docroot

1. Check to see if the file is in your client's cache.
2. Tomcat does nothing with these tags. Your client may ignore them

Markus,
Im using Tomcat 5.5.17. I assumed that my browser would send the

does.

Markus,
I have fixed the problem. I needed to set the contenttype and the

Thanks for your input.
