I have a Perl cgi that serves an xhtml page including, as <object> 
(no embed) an SVG drawing whose specs can be changed by submitting 
data from an html form.  The form and the drawing begin with the 
default specs and both are updated as the user makes successive 
changes to his requirements.

I am doing most of my testing in Mac OS 10 with FireFox (in fact the 
beta 3.**) and there is no problem with local caching here or in 
Safari, but Opera puts the SVG file into its cache so that the user's 
modifications are not updated in the drawing. I have so far found no 
way to prevent this behaviour with meta tags in the html and the only 
way for the thing to be usable in Opera is for the user to delete the 
cache before submitting the changed data.

Can anybody suggest a solution to this?
