Multiple Proxy Authentications Required

SveN_01
Hi,
I have a strange with Problem with the Proxy Authentication.
If I receive a HTML-Email my Mailclient saves the HTML file
in my temporary folder and displays it with with Internet Explorer.
If the File contains images Internet Explorer asks for every Image
for Authentication. If I use Firefox it asks only once (as exprected).

Sample:

IE8 aks 3 times, Firefox only once...

Maybe someone has an idea how I could tell IE to behave as Firefox?

    SveN, What do you see in the 'Content Filter (HTTP/S)' log when this occurs with each browser?  Is there any difference in the 'User Authentication' log other than the fact that there are three auths instead of one?

    Cheers - Bob

    Hi,
    this happens on all machines having Internet Explorer installed.

    the HTTP log says: 
    2011:07:14-17:08:54 server httpproxy[4207]: id="0001" severity="info" sys="SecureWeb" sub="http" name="http access" action="pass" method="GET" srcip="192.168.56.114" user="myname" statuscode="304" cached="0" profile="REF_DefaultHTTPProfile (Default Proxy)" filteraction="REF_DefaultHTTPCFFAction (Default content filter action)" size="0" time="63 ms" request="0xaa836398" url="www.abafa.net/1.jpg" exceptions="" error="" category="9998" reputation="neutral" categoryname="Uncategorized"

    2011:07:14-17:08:54 server httpproxy[4207]: id="0001" severity="info" sys="SecureWeb" sub="http" name="http access" action="pass" method="GET" srcip="192.168.56.114" user="myname" statuscode="304" cached="0" profile="REF_DefaultHTTPProfile (Default Proxy)" filteraction="REF_DefaultHTTPCFFAction (Default content filter action)" size="0" time="60 ms" request="0xa11fba08" url="www.abafa.net/3.jpg" exceptions="" error="" category="9998" reputation="neutral" categoryname="Uncategorized"

    2011:07:14-17:08:55 server httpproxy[4207]: id="0001" severity="info" sys="SecureWeb" sub="http" name="http access" action="pass" method="GET" srcip="192.168.56.114" user="myname" statuscode="304" cached="0" profile="REF_DefaultHTTPProfile (Default Proxy)" filteraction="REF_DefaultHTTPCFFAction (Default content filter action)" size="0" time="36 ms" request="0xa11fba08" url="www.abafa.net/2.jpg" exceptions="" error="" category="9998" reputation="neutral" categoryname="Uncategorized"


    and the aua.log 
    2011:07:14-17:09:55 server aua[18238]: id="3006" severity="info" sys="System" sub="auth" name="Trying 192.168.56.201 (edirectory)"

    2011:07:14-17:09:56 server aua[18238]: id="3004" severity="info" sys="System" sub="auth" name="Authentication successful" srcip="192.168.56.5" user="myname" caller="http" engine="edirectory"


    Looks a little strange that the aua.log says it Authenticates only once...
