Summary

Function: llSetContentType( key request_id, integer content_type );

Set the "Wikipedia logo" Internet media type of an LSL HTTP server response.[1]

• key request_id – a valid http_request() key
• integer content_type – Media type to use with any following llHTTPResponse(request_id, ...)

content_type Content-Type
CONTENT_TYPE_TEXT 0 text/plain
CONTENT_TYPE_HTML 1 text/html
CONTENT_TYPE_XML 2 application/xml
CONTENT_TYPE_XHTML 3 application/xhtml+xml
CONTENT_TYPE_ATOM 4 application/atom+xml
CONTENT_TYPE_JSON 5 application/json
CONTENT_TYPE_LLSD 6 application/llsd+xml
CONTENT_TYPE_FORM 7 application/x-www-form-urlencoded
CONTENT_TYPE_RSS 8 application/rss+xml

Caveats

  • When using CONTENT_TYPE_HTML, this setting will be ignored unless all of these conditions are met:
    1. the web browser is the Second Life client
    2. the user (logged into the SL client viewing the page) is the owner of the object.
    3. the user (logged into the SL client viewing the page) is connected to the region the object is located in
    Obviously this is not compatible with group owned objects. One way around this limitation would be to temporarily attach a repeated.

My First Heading

My first paragraph.

</body> </html>";

default {

   http_request(key id, string method, string body)

       vector ownerSize = llGetAgentSize(owner);

       if (url_request == id)

           if (method == URL_REQUEST_GRANTED)

               llOwnerSay("URL: " + body);

           //  if owner in sim
               if (ownerSize)//  != ZERO_VECTOR
                   llLoadURL(owner, "I got a new URL!", body);

               llHTTPResponse(id, 200, HTML_BODY);
           }

               llSetContentType(id, CONTENT_TYPE_TEXT);

Comments

The client and owner limitations are most likely to remove the possibility of running a website from a prim.
