[sldev] Web Textures and error responses: pass error handling into http_response

[SignpostMarv Martin]

Problem: JPEG requested, server refuses or fouls up request. What gets displayed ?

Potential solution:

Use an LSL function to request an asset UUID for a given URL.
* key llRequestWebTexture(string url);

* request headers similar to those sent with llHTTPRequest() would be sent (thus allowing servers to allow/deny based on the Requesting Resident, region of origin etc.) If the fetch gets a 200, the texture can immediately be used with llSetTexture() etc. Any other code then fires off http_response(), where the request_id parameter matches the one returned by llRequestWebTexture(). This would then allow scripts to make intelligent responses based on standard HTTP response codes (401, 402, 403) http://en.wikipedia.org/wiki/List_of_HTTP_status_codes#4xx_Client_Error

Caveats:

1) Would require HTTP asset server & viewer to support 301/302 redirects



~ Marv.

Retaining the ability for the viewer to disable 3rd-party web textures would then be switched to not obeying 301/302 redirects. 2) Would likely force LL to impose file size restrictions (no multi-megabyte poorly compressed PNG/MNG/aPNG)
