Sometimes you will need to send static files over http using ASP.Net - for example if you want to control access to the file programmatically. Such tasks can be simply handled by Response.WriteFile(FileName) for plain html files, but there are two problems:
1. GetContentType - returns content-type of a file from registry 2. DateFromHTTP - converts string date from http header (Fri, 09 Sep 2005 07:51:28 GMT format) to Date format 3. DateToHTTPDate - converts date to string format.
See alsofor 'Work with If-Modified-Since and Last-Modified in ASP.Net.' article How to convert http date to OLE(VB/VBS) date.ASP (VBS) function converting http string date (like Fri, 22 Oct 1999 12:08:38 GMT) to DATE data type.How to convert DATE to a HTTP string date in ASPASP (VBS) function converting DATE data type to http string date (like Fri, 22 Oct 1999 12:08:38 GMT).
