DateTimeToHTTP(datetime)
Description
Use the DateTimeToHTTP function to convert any DateTime value to a date/time string in the format specified by HTTP 1.0 and 1.1 standards.
Note: Because the HTTP protocol is used to interchange information between diverse computing systems, the value returned from this function is always the âUS Englishâ form of weekdays and months. If you want the value to use the localized form, use the DateTimeToLocalizeString function instead.
The standard HTTP date/time has the following fixed length format:
<dow><,><sp><dd><sp><mon><sp><year><sp><hh><:><mm><:><ss><sp><GMT>where:
