>>>Hi,
>>>
>>>I have a custom who still uses IE 6.0. When I connect to their server (via RDT) and try to download a file from my site I get the old version of the file. I can't seem to figure how to clear the buffer so that the IE would download the current file from my site. I tried Tools -> Internet Options -> Delete Files. But that does not clear the buffer. I tried to clear the history but that does nothing either. What else can I try?
>>What protocol are you using to download the file? If you're using FTP then you might try performing a Refresh (it may require several attempts) to re-load file listings before you initiate the transfer.

>I am download the file as following http://www.mysite.com/folder/filename.zip I do this with many customers but only this one has the cache in the browser "stock" and no matter what I do I get the old version of the file.

Try removing the zip file from your site and the customer to try downloading it and getting the error. Then place the file back again.
