IIS - Other - ** Caching of Applet & Web Server Logging **

All,
Can you please provide me some details of the server/client behavior under the following scenario's in using an Applet?

Web Server used -- IIS 6.0

I am using the <Applet> tag to embed the applet in my aspx page. I had included the following parameters for applet caching.

<param name = "cache_option" value = "Plugin" />
<param name = "cache_archive" value = "DownloadManager.jar" />

Now as per the documentations for the above parameters, subsequent loading of the Applet in the browser will happen using the local copy! Now looking into the HTTP status code logging on the server.

I got the following server response code while accessing the portal the first time after clearing the browser/Java plugin cache

2008-04-09 11:49:56 W3SVC335036309 192.23.184.175 GET /DownloadManager.jar - 80 - 163.185.27.3 Mozilla/4.0+(Windows+XP+5.1)+Java/1.6.0 200 0 0

From the above loggin, the server returned a status code of 200 (last few digits of the previous line) which meant that the server sent back the jar file successfully.

Now for the subsequent access of the same portal, I had got the following log on server side
2008-04-09 12:00:15 W3SVC335036309 192.23.184.175 GET /DownloadManager.jar - 80 - 192.23.8.48 Mozilla/4.0+(Windows+XP+5.1)+Java/1.6.0_05 304 0 0

According to the above log file, the server had responded with status code 304 (last few digits of the previous line) , which means that the browser is using the local copy of the Applet.

Now my questions are

1. Is my interpretation of the server loggin right?
2. Is the inclusion of <param> attributes for specifying the applet caching right? If not can you please give me pointers to acheive the same?

Amrish Deep
