[Twisted-web] sending svg code from livepage

Hi all, I would like to display svg which is generated on the server side, I tried to do so with nevow and livepage but i experienced some problems... i tried both sending the code embedded in a <embed> and <object > tag but none of this worked... when i use a iframe to display the svg it gets all screwed up and no graphics are shown.... i was wondering if this was related to nevow/twisted as if i just point my browser (firefox) to the file ... it works just fine! thanks for any help!
