I'm using Tomcat 3.2.2 on vanilla AIX 4.3.3 and IBM's "jdk" 1.3. I
suspect the "If-Modified-Since" qualifier on HTTP GET operations is being
ignored. Could this be true, and if so, can I make Tomcat pay attention
to it? I could not find this issue addressed in the User's Guide nor the
FAQ, nor fully well in the archive at mail-archive.com.
Using the TcpTunnelGui included with SOAP, I captured the following
exchange. Here is the GET request:
GET /stylesheet/style.css HTTP/1.0
If-Modified-Since: Fri, 22 Jun 2001 19:18:56 GMT; length=2916
Connection: Keep-Alive
User-Agent: Mozilla/4.75 [en] (Windows NT 5.0; U)
Host: alphaspreit:9000
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, image/png,
*/*
Accept-Encoding: gzip
Accept-Language: en,pdf
Accept-Charset: iso-8859-1,*,utf-8
Cookie: JSESSIONID=0bzu6rxaj1
and here are the headers from a GET response (I strongly suspect, but am
not 100% certain, it is the response to the GET above --- I've been having
some trouble with the TcpTunneGui):
HTTP/1.0 200 OK
Content-Type: text/plain
Content-Length: 2916
Last-Modified: Fri, 22 Jun 2001 19:18:56 GMT
Servlet-Engine: Tomcat Web Server/3.2.2 (JSP 1.1; Servlet 2.2; Java 1.3.0;
AIX 4.3 ppc; java.vendor=IBM Corporation)
