2216 | * The Authorizer application receives HTTP request information from the Web | |
2217 | * server on the FCGI_PARAMS stream, in the same format as a Responder. The | |
2218 | * Web server does not send CONTENT_LENGTH, PATH_INFO, PATH_TRANSLATED, and | |
2219 | * SCRIPT_NAME headers. | |
2220 | * === | |
2221 | * Ergo if we are in Authorizer role, we MUST look at HTTP_CONTENT_LENGTH | |
2222 | * instead of CONTENT_LENGTH for the Content-Length. | |
2223 | * | |
2224 | * There is one slight wrinkle in this, and that's older versions of | |
2225 | * nginx/lighttpd/apache setting BOTH headers. As a result, we have to check | |
2226 | * both headers and can't always simply pick A or B. | |
