Need some help here.
I've recently migrated a site from an MPLS link that ultimately fed out a SmartCity Internet circuit to a local circuit provided by PowerOne. The network goes through a Cisco ASA5520 to go out the PowerOne circuit.
The Marketing Department uses the website
http://www.123rf.com, a subscription-based royalty free image site, to download images that they use for marketing materials. Each image is available in a number of formats - Blog, Web, Print, Ultra High, and Mega High. The resolution/quality/size of each increases as you move up that scale.
The issue we have presently is that the Print, Ultra High, and Mega High images fail to download, returning a "Internet Explorer cannot display the webpage" error almost immediately after clicking the associated Download link. Firefox blows up as well. The Blog and Web files download fine.
Additional notes/things I've investigated -
* It is not just large files in general. I was able to download the installer for OpenOffice.Org's productivity suite (150MB) without an issue, and on the first attempt. By contrast, the "Print" quality image at 123rf.com of most images is in the 12MB Raw file size.
* It is not browser specific or OS specific. The issue was first reported by a Macintosh/Firefox combination, but has also been replicated on XP/Firefox, XP/IE, W2K/IE.
* The issue started after we moved to the ASA/PowerOne combination. This worked fine when routing through the MPLS to SmartCity.
* The ASA doesn't look like it's causing a problem. I have attached log information from it, Debugging Level, that looks identical for a successful download of one of the smaller files as compared to a failed download of a larger file.
* The Support people for 123rf.com say everything is working fine from their end (don't they always)?
Thoughts? Looking for assistance on who to pressure - Web Site Support, Cisco, PowerOne.
Thanks.
