Preprocessing Directives
Active Server Pages provides
preprocessing directives similar to the
compiler directives in C and similar languages. Like these
precompilation directives, ASP directives instruct the web server to
perform a function before the script is completed and sent to the
client. The web server performs the other directives before
interpreting the script itself. ASP directives, with the exception of
<%=
expression
%>, must appear on the first line of a script
and cannot be included using a Server-Side Included file. The format
for these directives (with the aforementioned exception of the
<%=
expression
%> directive) is the following:
<%@ DIRECTIVE=Value%>where DIRECTIVE is one of the ASP directives
listed in this section and Value is a
valid value for the directive. Note that you must include a space
between the @ character and the directive. Also
note that the preprocessing directive must be placed within
<%...%> delimiters.
The valid ASP preprocessing directives are listed as follows and are explained in depth later in this chapter:
| CODEPAGE |
| ENABLESESSIONSTATE |
| LANGUAGE |
| LCID |
| TRANSACTION |
