cfcontent 89
Usage
To set the character encoding (character set) of generated output, use code such as the following:
<cfcontent type="text/html; charset=ISO-8859-1">
When ColdFusion processes an HTTP request, it determines the character encoding of the data
returned in the HTTP response. By default, ColdFusion returns character data using the Unicode
UTF-8 format (regardless of the value of an HTML
meta
tag in the page). You can use the
cfcontent
tag to override the default character encoding of the response. For example, to specify
the character encoding of the page output as Japanese EUC, use the
type
attribute, as follows:
<cfcontent type="text/html; charset=EUC-JP">
If you call the
cfcontent
tag from a custom tag, and you do not want the tag to discard the
current page when it is called from another application or custom tag, set
reset
= "no".
If a file delete operation is unsuccessful, ColdFusion throws an error.
If you use this tag after the
cfflush
tag on a page, ColdFusion throws an error. The following tag
can force most browsers to display a dialog that asks users whether they want to save the contents
of the file specified by the
cfcontent
tag as a with the filename specified by the
filename
value.
cfheader name="Content-Disposition" value="attachment;
filename= filename.ext "
For many file types, such as Excel documents, that Internet Explorer can display directly in the
browser, the browser displays the file without asking users whether to save it if you use a
cfheader
tag similar to the following:
<cfheader name="Content-Disposition" value="filename= filename.ext ">
For more information on character encodings, see the following web pages:
•
www.w3.org/International/O-charset.html provides general information on character
encodings and the web, and has several useful links.
•
www.iana.org/assignments/character-sets is a complete list of character sets names used on the
Internet, maintained by the Internet Assigned Numbers Authority.
•
java.sun.com/j2se/1.3/docs/guide/intl/encoding.doc.html lists the character encodings that
Java, and therefore ColdFusion, can interpret. This list uses Java internal names, not the IANA
character encoding names that you use in the
SetEncoding charset
parameter and other
ColdFusion attributes and parameters.

Example
<!--- This example shows the use of cfcontent to return the contents of the CF
Documentation page dynamically to the browser.
You might need to change the path and/or drive letter depending on how
ColdFusion is installed on your system.
Notice that the graphics do not display and the hyperlinks do not work,
because the html page uses relative filename references.
The root of the reference is the ColdFusion page, not the location of the
html page.
<cfcontent type = "text/html"
file = "C:\CFusionMX\wwwroot\cfdocs\dochome.htm"
deleteFile = "No">
<!--- This example shows how reset attribute changes text output. --->
