contentType application/vnd.ms-excel does not work in IE7

Hi I have developed a following VF page
<apex:page sidebar="false"  controller="BES_exportCasesToCSVController" contentType="application/vnd.ms-excel#Cases.xls">
    <apex:PageBlock >
        <apex:PageBlockTable value="{!cases}" var="case" rowClasses="odd,even" styleClass="tableClass" >
           <apex:column >
                <apex:facet name="header">Practice Name</apex:facet>
                <apex:outputText value="{!case.Practice_Name__r.Name}"/>
            </apex:column>
        </apex:PageBlockTable>
    </apex:PageBlock>
</apex:page>

This gives me excel file for the pageBlockTable contents when I execute this in Firefox 
or Google Chrome browser,but when I run this in IE 7 an error box pops up displaying following
message 
---------------------------
Windows Internet Explorer
---------------------------
Internet Explorer cannot download exportCasesToCSV from c.cs2.visual.force.com.



Internet Explorer was not able to open this Internet site.  The requested site is either unavailable or cannot be found.  Please try again later.
---------------------------
OK   
---------------------------

I need this working in IE because client uses IE7. Pls tell me any workarounf for this. I am ready to go for SControl 
also if there is no way in VisualForce

I know this is an old thread, but I fixed this problem by adding the cache="true""attribute to the apex:page attributes:

 

<apex:page standardController="xxx__c" sidebar="false" cache="true" contenttype="application/vnd.ms-excel">

See this post - IE7 has some interesting issues around HTTPS and cache headers etc. We are aware of this and at some point in the future the workaround will not be necessary.
