Summary

Function: llSetContentType( key request_id, integer content_type );

Sets the Internet media type "Content-Type" header of any subsequent LSL HTTP server response via llHTTPResponse.

• 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 0x0 text/plain
CONTENT_TYPE_HTML 0x1 text/html
CONTENT_TYPE_XML 0x2 application/xml
CONTENT_TYPE_XHTML 0x3 application/xhtml+xml
CONTENT_TYPE_ATOM 0x4 application/atom+xml
CONTENT_TYPE_JSON 0x5 application/json
CONTENT_TYPE_LLSD 0x6 application/llsd+xml
CONTENT_TYPE_FORM 0x7 application/x-www-form-urlencoded
CONTENT_TYPE_RSS 0x8 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.

Comments

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