A guy is selling HTTP error pages and he claims that one page can dynamically display all kind of http errors and replace all my current default ispconfig error pages. It is possible?
yes sure, very simple since your webserver allows to specify pages to be used for given errors like it is done already. and of course you can set a dynamic.file?withErrorCode=tobedefined as target. Or use some rewrite rules... there are plenty solutions explained out there. if that guy wants money, it better be pretty sexy looking error pages
