SEND HTTP REDIRECT
| SEND HTTP REDIRECT ( url {; *} ) | ||||||||
| Parameter | Type | Description | ||||||
| url | String |
|
New URL | |||||
| * | Operator |

If specified = URL is not translated, If omitted = URL is translated | |||||
The SEND HTTP REDIRECT command allows you to transform a URL into another one.
The url parameter contains the new URL that allows you to redirect the request. If this parameter is a url to a file, it must contain the reference to this file, for example: SEND HTTP REDIRECT ("/MyPage.HTM").
This command prevails over commands that send data (SEND HTML FILE, SEND HTML BLOB, etc.) that may be in the same method.
This command also allows you to redirect a request to another Web server.
4D automatically encodes the URL’s special characters. If you pass the * character, 4D will not translate them.
Note that the status of the request sent by this command is 302: Moved Temporarily. If you need a "moved permanently" status (status 301), you can set a HTTP X-STATUS: 301 field in the header of the reply.
You can use this command to execute custom requests in 4D by using static pages. Imagine that you have placed the following elements in a static HTML page:
Note: The POST action “/4dcgi/rech” has been associated to the text area and to the OK and Cancel buttons.
In the On Web Connection Database Method, you insert the following code:
Case of
:($1="/4dcgi/rech") `When 4D receives this URL
`If the OK button has been used and the ‘name’ field contains a Value
If((bOK="OK") & (name#""))
`Change the URL to execute the request code,
`placed farther down in the same method
SEND HTTP REDIRECT("/4dcgi/rech?"+name)
Else
`Else return to the beginning page
SEND HTTP REDIRECT("/page1.htm")
End if
...
:($1="/4dcgi/rech?@") `If the URL has been redirected
... `Put the request code here
End case
