[config] opts for http header parsing strictness (fixes #551, fixes #1086, fixes #1184, fixes #2143, #2258, #2281, fixes #946, fixes #1330, fixes #602, #1016) server.http-parseopt-header-strict = "enable" server.http-parseopt-host-strict = "enable" (implies host-normalize) server.http-parseopt-host-normalize = "disable" defaults retain current behavior, which is strict header parsing and strict host parsing, with enhancement to normalize IPv4 address and port number strings. For lighttpd tests, these need to be enabled (and are by default) For marginally faster HTTP header parsing for benchmarks, disable these. To allow - underscores in hostname - hypen ('-') at beginning of hostname - all-numeric TLDs server.http-parseopt-host-strict = "disable" x-ref: "lighttpd doesn't allow underscores in host names" "hyphen in hostname" "a numeric tld" "Numeric tld's" "Bad Request" "400 Bad Request when using Numeric TLDs" To allow a variety of numerical formats to be converted to IP addresses server.http-parseopt-host-strict = "disable" server.http-parseopt-host-normalize = "enable" x-ref: "URL encoding leads to "400 - Bad Request"" "400 Bad Request when using IP's numeric value ("ip2long()")" To allow most 8-bit and 7-bit chars in headers server.http-parseopt-header-strict = "disable" (not recommended) x-ref: "Russian letters not alowed?" "header Content-Disposition with russian '?' (CP1251, ascii code 255) causes error"

[core] server.error-handler new directive for error pages (fixes #2702) server.error-handler preserves HTTP status error code when error page is static, and allows dynamic handlers to change HTTP status code when error page is provided by dynamic handler. server.error-handler intercepts all HTTP status codes >= 400 except when the content is generated by a dynamic handler (cgi, ssi, fastcgi, scgi, proxy, lua). The request method is unconditionally changed to GET for the request to service the error handler, and the original request method is later restored (for logging purposes). request body from the original request, if present, is discarded. server.error-handler is somewhat similar to server.error-handler-404, but server.error-handler-404 is now deprecated, intercepts only 404 and 403 HTTP status codes, and returns 200 OK for static error pages, a source of confusion for some admins. On the other hand, the new server.error-handler, when set, will intercept all HTTP status error codes >= 400. server.error-handler takes precedence over server.error-handler-404 when both are set. NOTE: a major difference between server.error-handler and the now-deprecated server.error-handler-404 is that the values of the non-standard CGI environment variables REQUEST_URI and REDIRECT_URI have been swapped. Since REDIRECT_STATUS is the original HTTP status code, REDIRECT_URI is now the original request, and REQUEST_URI is the current request (e.g. the URI/URL to the error handler). The prior behavior -- which reversed REQUEST_URI and REDIRECT_URI values from those described above -- is preserved for server.error-handler-404. Additionally, REDIRECT_STATUS is now available to mod_magnet, which continues to have access to request.uri and request.orig_uri. See further discussion at and github: closes #36
