MMHttp.getFile()

Description Gets the file at the specified URL and saves it in the Configuration/Temp folder inside the Dreamweaver application folder on the user's hard drive. Dreamweaver automatically creates subfolders that mimic the directory structure of the server; for example, if the specified file is at http://www.dreamcentral.com/people/index.html, Dreamweaver stores the index.html file in the people folder inside the www.dreamcentral.com folder.
Arguments URL, {prompt}, {saveURL}, {titleBarLabel}
The first argument is an absolute URL on a web server; if the "http://" part of the URL is omitted, it is assumed.
The second argument is a Boolean value that specifies whether to prompt the user to save the file. If saveURL is outside the Configuration/Temp folder, a prompt value of FALSE is ignored for security reasons.
The third argument is the location on the user's hard drive where the file should be saved, expressed as a file:// URL. If prompt is TRUE or saveURL is outside the Configuration/Temp folder, the user can override saveURL in the Save dialog box.
The fourth argument is the label that should appear in the title bar of the Save dialog box.
Returns An object that represents the reply from the server. The data property of this object is a string containing the location at which the file was saved, expressed as a file:// URL. Normally the statusCode property of the object contains the status code received from the server. However, if a disk error occurs while saving the file on the local drive, the statusCode property contains an integer representing one of the following error codes if the operation was not successful:
1: Unspecified error
2: File not found
3: Invalid path
4: Number of open files limit reached
5: Access denied
6: Invalid file handle
7: Cannot remove current working directory
8: No more directory entries
9: Error setting file pointer
10 Hardware error
11: Sharing violation
12:Lock violation
13: Disk full
14: End of file reached
Example The following code gets an HTML file, saves all the files in the Configuration/Temp folder, and then opens the local copy of the HTML file in a browser: 
var httpReply = MMHttp.getFile("http://www.dreamcentral.com/people/profiles/scott.html",
false);
if (httpReply.statusCode == 200){
  var saveLoc = httpReply.data;
  dw.browseDocument(saveLoc);
}
