Reviewing the code
The following table describes the code and its function:
To return results of a CGI program:
The following code runs a CGI program search.exe on a website and displays the results,
including both the MIME type and length of the response. The search.exe program must expect a
“search” parameter.
<cfhttp method="Post"
url="http://www.my_favorite_site.com/search.exe"
resolveurl="Yes">
<cfhttpparam type="Formfield"
name="search"
value="Macromedia ColdFusion">
</cfhttp>
<cfoutput>
Response Mime Type: #cfhttp.MimeType#<br>
Response Length: #len(cfhttp.filecontent)# <br>
Response Content: <br>
#htmlcodeformat(cfhttp.filecontent)#<br>
</cfoutput>
Code Description
<cffile destination="C:\temp\"

attributes="Normal">
Write the transferred document to a file on the server.
You send the file using the

request.
The Cookie variable is:
#Cookie.mycookie# <br>
Output the value of the Cookie variable sent in the
