When designing an HTML <FORM> with large text blocks for submission to a 4D database, be sure to use an HTML POST action not an HTML GET action. Each browser restricts the number of characters that can be submitted via the GET action. IE 5.5 on Windows is around 1400 characters, Netscape on Mac around 3800.
Using a POST action raises these limits. IE will allow about 20,000 characters with a POST and Netscape has even higher value.
