Http-Status-Code-403
啟用 mod_security 後 URL 損壞
例如這個 pdf 在啟用 mod 後停止工作，它會產生 403 錯誤。

您應該有一個
modsecurity_crs_10_config.conf如下所示的部分：# # -=[ HTTP Policy Settings ]=- # # Set the following policy settings here and they will be propagated to the 30 rules # file (modsecurity_crs_30_http_policy.conf) by using macro expansion. # If you run into false positves, you can adjust the settings here. # SecAction "phase:1,id:'981212',t:none,nolog,pass, \ setvar:'tx.allowed_methods=GET HEAD POST OPTIONS', \ setvar:'tx.allowed_request_content_type=application/x-www-form-urlencoded multipart/form-data text/xml application/xml application/x-amf', \ setvar:'tx.allowed_http_versions=HTTP/0.9 HTTP/1.0 HTTP/1.1', \ setvar:'tx.restricted_extensions=.asa/ .asax/ .ascx/ .axd/ .backup/ .bak/ .bat/ .cdx/ .cer/ .cfg/ .cmd/ .com/ .config/ .conf/ .cs/ .csproj/ .csr/ .dat/ .db/ .dbf/ .dll/ .dos/ .htr/ .htw/ .ida/ .idc/ .idq/ .inc/ .ini/ .key/ .licx/ .lnk/ .log/ .mdb/ .old/ .pass/ .pdb/ .pol/ .printer/ .pwd/ .resources/ .resx/ .sql/ .sys/ .vb/ .vbs/ .vbproj/ .vsdisco/ .webinfo/ .xsd/ .xsx/', \ setvar:'tx.restricted_headers=/Proxy-Connection/ /Lock-Token/ /Content-Range/ /Translate/ /via/ /if/'"你能在你的問題中加上你的那行
allowed_http_versions嗎？或者更好的是，整個部分？您的 Apache 訪問日誌中針對同一請求的日誌行可能也很有用，但我懷疑僅使用配置中的 allowed_http_versions 行就可以獲得足夠的資訊。
錯誤消息包含
[data "HTTP/1.1"]指示規則已被觸發，因為HTTP/1.1它不是允許的 HTTP 版本之一。要麼你allowed_http_versions不包含HTTP/1.1，要麼有其他東西弄亂了那組規則，這意味著變數設置不正確。
