I&#039;m trying to program an ISAPI filter with Visual C++ 6.0. Our web site runs under IIS 5.0 and Win2K.<BR><BR>The purpose of this filter is to modify the content of the HTML code that is sent to the client. The problem is that the page doesn&#039;t load because the value of the Content-length field sent in the header doesn&#039;t match the length of the new document.<BR>And I can&#039;t change this value because the header is already sent when I know the new size.<BR><BR>The only way I managed to load the page is to disable the keep-alive option. But I&#039;m looking for a better way to do this.<BR><BR>Any help will be appreciated.<BR><BR>Fred<BR>
