We created a new media this morning for this client. When we preview the media we get the attached error. We verified the URL to the clients website and it works. We created another new media and got the same error.

    Can you tell me the ID# or name of the media so I can take a look at it? I'm guessing there is something in the link our system may be falsely identifying as an XSS exploit. That is usually why a 400 error will occur.

    Here's a screen shot of the media.

    Hi Gregg,

    Ok, the problem here is our XSS filter detects the pattern 'onwheel' as a potential JavaScript event exploit and it's contained in the word 'wagonwheel'

    I made a change to media #3,877 to get it working though. You'll see what I did was define a HTML code for the banner, which doesn't pass the actual link to the advertisers site over the wire. That avoids it getting scanned by our XSS filter so it doesn't get blocked.

    Although that works I'm going to look into a better solution for this since it's inconvenient to have to implement a workaround.
