我有以下的清漆configuration：
backend default { .host = "127.0.0.1"; .port = "8080"; } acl purge { "127.0.0.1"; } sub vcl_recv { #cloudflare remove req.http.X-Forwarded-For; if (req.http.cf-connecting-ip) { set req.http.X-Forwarded-For = req.http.cf-connecting-ip; } else { set req.http.X-Forwarded-For = client.ip; } # Remove has_js and CloudFlare/Google Analytics __* cookies. set req.http.Cookie = regsuball(req.http.Cookie, "(^|;\s*)(_[_a-z]+|has_js)=[^;]*", ""); # Remove a ";" prefix, if present. set req.http.Cookie = regsub(req.http.Cookie, "^;\s*", ""); # Let's make sure we aren't compressing already compressed formats. if (req.http.Accept-Encoding) { if (req.url ~ "\.(jpg|png|gif|gz|tgz|bz2|mp3|mp4|m4v)(\?.*|)$") { remove req.http.Accept-Encoding; } elsif (req.http.Accept-Encoding ~ "gzip") { set req.http.Accept-Encoding = "gzip"; } elsif (req.http.Accept-Encoding ~ "deflate") { set req.http.Accept-Encoding = "deflate"; } else { remove req.http.Accept-Encoding; } } if (req.request == "PURGE") { if (!client.ip ~ purge) { error 405 "Not allowed."; } return(lookup); } if (req.url ~ "^/$") { unset req.http.cookie; } } sub vcl_hit { if (req.request == "PURGE") { set obj.ttl = 0s; error 200 "Purged."; } } sub vcl_miss { if (req.request == "PURGE") { error 404 "Not in cache."; } if (!(req.url ~ "wp-(login|admin)")) { unset req.http.cookie; } if (req.url ~ "^/[^?]+.(jpeg|jpg|png|gif|ico|js|css|txt|gz|zip|lzma|bz2|tgz|tbz|html|htm)(\?.|)$") { unset req.http.cookie; set req.url = regsub(req.url, "\?.$", ""); } if (req.url ~ "^/$") { unset req.http.cookie; } } sub vcl_fetch { if (req.url ~ "^/$") { unset beresp.http.set-cookie; } if (!(req.url ~ "wp-(login|admin)")) { unset beresp.http.set-cookie; } } sub vcl_pipe { set bereq.http.connection = "close"; if (req.http.X-Forwarded-For) { set bereq.http.X-Forwarded-For = req.http.X-Forwarded-For; } else { set bereq.http.X-Forwarded-For = regsub(client.ip, ":.*", ""); } } sub vcl_pass { set bereq.http.connection = "close"; if (req.http.X-Forwarded-For) { set bereq.http.X-Forwarded-For = req.http.X-Forwarded-For; } else { set bereq.http.X-Forwarded-For = regsub(client.ip, ":.*", ""); } } 当我的networking应用程序连接到许可证服务器时，我得到“无效许可证密钥”。 如果我把清漆的一切工作。 有什么可能会出错？
