I have a VB program that builds HTML pages with links to PDF files. This system, prior to building the file, checks whether there are several versions of the PDF files. If there is only one version, the built HTML page contains a <META http-equiv=refresh> statement which automatically redirects the browser to the relevant .PDF file. If the program finds two or more versions, the HTML file is built as a menu and the user can select the relevant version of the document. This works fine. The problem arise when the user wants to go back to the calling page and hits the 'Previous page'-button in the browser. In cases where there is only one version the user is brought back to the HTML page with the <meta>-tag and is immediately redirected to the PDF. Even clicking the backwards-button quickly twice doesn't help. Is there an elegant solution to this that I can implement?
