In our environment we have lotus notes, and it doesn't handle NTLM authentication very well, ok not at all. So users often will open an email that has webcontent in it, mainly images, and when they type their password in wrong, it displays red x's in a box for the image. Is there a way to have a gif or jpg image sent back to notes so that we could inform the user of the error? I am sure that what is getting passed back is the Cache Access Denied page. Is squid capable of knowing that the browser is looking for an other filetype than txt/html? Thank you, Brian
