Have a single ptviewer jar file per website
Typically it is embedded in a web-page using applet or object HTML tags, the ptviewer.jar file location is specified in the archive attribute:
<applet archive="/path/to/ptviewer.jar" code="ptviewer.class" width="320" height="200"> <param name="file" value="panorama.jpg" /> </applet>
This has caused problems in the past with some Java virtual machines which have interpreted the archive path differently, generally web-site creators place the JAR archive in the same directory as the HTML page and specify the location like so:
To avoid having superfluous copies of the applet on a server, you can use this apache directive to make it appear that a single copy appears to exist in every directory:
RewriteEngine on RewriteRule (^|/)ptviewer\.jar$ /websites/mysite/html/ptviewer.jar
(replace /websites/mysite/html/ptviewer.jar with the system path on your server)
This requires apache with mod_rewrite enabled. You can place the directive in the httpd.conf configuration file or in a ?htaccess file in the root of your site.
