Bug: Link encoding issues for advertiser

[brent]

Fertilaid wants us to link our ads to a yahoo store site using the following link: http://store.yahoo.com/cgi-bin/clink?yhst-10669596438250+CMS5PF+fertility.html

This link causes issues with openx so faisal created a URL encoder utility located at http://scripts.healthguru.com/admin/basictools to encode the link to work in our system.

The tool spit out the url: http%3A%2F%2Fstore.yahoo.com%2Fcgi-bin%2Fclink%3Fyhst-10669596438250%2BCMS5PF%2Bfertility.html

This worked previously but now is causing the following error message when clicked from our site:

---

There appears to be a specific problem with the header redirection coming from the link. I believe the problem (but I have not confirmed this, it's more of a hunch) is that the yahoo store is setting a header redirect on the link, which is what OpenX is also doing. The error is actually occurring when Yahoo Stores tries to redirect the link, OpenX has already set and changed the header location.

One work-around is to instead use http://www.fairhavenhealth.com/fertility.html directly.

Currently checking if all such redirections cause problems for OpenX.

Found a way around this. The problem was that the notice message being generated caused output to be produced which made the header function call fail. The notice message was generated because the url was a non-standard type.

By suppressing notices using error_reporting(1), this problem is side-stepped.
