fancybox makes multiple request on iframe

Question

I'm using the fancybox v2.1.5 for a .net application. I use the iframe for displaying an aspx-side. Works fine. But today I noticed, that the request to my aspx-page to be displayed in a fancybox was made 4 times. I tested it with another page - same issue.

Here is all what I do:

<a href='ChangePassword.aspx' class="fancybox fancybox.iframe" style="color:white;text-decoration:none;">Change password</a>

This is the easy side, but in another there are some DB-Calls an many lines of code, so it isn't really a good thing because of the performance.

I've only found one very old link: google groups
