Re: Web Tookit Problem - Still!

Frank,

I tried the same thing and made a stand alone procedure like yours but still got the same result I've been getting - the header was not changed. It was still text/html. I'm thinking that there is a configuration problem on the OAS. Don't know what else it could be. Maybe the other mime types (application/octet-stream & I also tried file/data) aren't defined on the OAS and need to be. Unfortunately I don't administer the OAS I use so it's a problem getting things changed.

Thanks for your help,
Milo
