I noticed that in Firefox I can add a #MyAnchor tag to the action attribute like...
<form action="#MyAnchor">
<input type="text" name="a" />
<input type="text" name="b" />
<input type="submit" />
</form>
and when the form is submitted, the anchor automatically shows up in the URL like
mypage.aspx?a=1&b=2#MyAnchor
However, this doesn't work on IE. Is there anyway I can find a happy medium for both browsers?
