Tip: Certain server environments (CGI) place headers into variables by capitalizing the entire name, replacing dashes with underscores, and prefixing the name with "HTTP_", e.g. "X-SecondLife-Object-Name" becomes "HTTP_X_SECONDLIFE_OBJECT_NAME". This depends solely on the HTTP server used to process the request and cannot be controlled via LSL.
⚠️ Warning: RFC 2616 § 4.2 defines HTTP header field names as case-insensitive. The capitalization of header field names shown above is not guaranteed; for example, "X-SecondLife-Object-Name" may be received as "X-Secondlife-Object-Name". See BUG-5094 for an instance of ISPs recapitalizing headers. This behavior was also observed when testing in 2026.
