Summary
Function: key llRequestURL( );| 0.0 | Forced Delay |
| 10.0 | Energy |
Requests one HTTP:// url for use by this object. The http_request event is triggered with the results.
Returns a key that is the handle used for identifying the request in the http_request event.
Caveats
- When a region is (re)started all HTTP server URLs are automatically released and invalidated.
- Use CHANGED_REGION_START to detect this so new URL can be requested.
- An old URL MUST be released first by using llReleaseURL if you are requesting an new one (where the reason for is not a region restart) or it will be still active and you are losing free URLs.
Examples
Requesting a new URL after region restart: <LSL> default {
state_entry()
{
//Requesting a URL
llRequestURL();
}
changed(integer What)
{
//Resgion restartet
if (What & CHANGED_REGION_START)
{
//Request new URL
llRequestURL();
}
}
http_request(key ID, string Method, string Body)
{
if (Method == URL_REQUEST_GRANTED)
{
//Saying URL to owner
llOwnerSay(Body);
}
else if (Method == URL_REQUEST_DENIED)
{
llOwnerSay("No URLs free !");
}
else if (Method == "GET")
{llHTTPResponse(ID, 200, "Hello there !");}
}
} </LSL> Here the old URL will be released anytime when the region restarts.
If you want to request a new URL and the region is not restarted you need to store the old one and release it manually before requesting a new one or your limit on free URLs will be down quick.
Try the following code ONLY if you can use all your URLs on your land. Removing the prim/script will release all URLs previous assigned. <LSL> default {
state_entry()
{
//Requesting a URL
llRequestURL();
}
http_request(key ID, string Method, string Body)
{
if (Method == URL_REQUEST_GRANTED)
{
//Printing new URL and free adresses
llSetText((string)llGetFreeURLs() + "\n" + Body, <1, 1, 1>, 1);
//Requesting a URL
llRequestURL();
}
else if (Method == URL_REQUEST_DENIED)
{
llSetText("No URLs free !", <1, 0, 0>, 1);
}
else if (Method == "GET")
{llHTTPResponse(ID, 200, "Hello there !");}
}
} </LSL> This script will, as you can see, use all URLs available on your land because it does not remove the old URLs before requesting a new one.
Just store the old URL in a global variable and release it with llReleaseURL.See Also
