I have a client who says when he visits his site from my directory he gets a 404 Object Not Found Error. I have given him a static html link and it works find from where I sit. Here are some particulars (or at least things I found strange).
1. In his email he mentions he has been working with a 'site name change' to help with 'search engine ranking' and it may be 'affecting my connection'.
2. The site uses frames and the framesets are called up via javascript located between the </head> and <body> tags.
3. <meta http-equiv="Cache-Control" content="must-revalidate"> (I'm not familiar with that but...)
Any ideas given the lack of specifics.
