Https website - security popup not getting disabled - page has a s

Hi

In my application we have ssl turned on with load balancer. my page has a
flash piece. so whenever the client opens the page a security warning pops
up. I wrote a custom http response filter to replace all the http:// with
https:// in my reponse. Even after replacing i still get the security popup.
Anyone has any idea how to turn off this securirty popup.

Thanks and Regards
Suba
