tomcat - URLRewriteFilter HTTP 到 HTTPS 规则返回 net::ERR_TOO_MANY_REDIRECTS

Question

我让 Tomcat 在带有 SSL 证书的 EC2 ELB 后面运行 URLRewriteFilter，ELB 将流量从端口 80 和 443 重定向到后端实例中的端口 8080。 URLRewriteFilter 有这个规则:

<rule>
    <condition type="scheme" operator="notequal">https</condition>
    <condition name="host" operator="equal">ELB-DNS</condition>
    <from>^/(.*)</from>
    <to type="permanent-redirect">https://ELB-DNS/$1</to>
</rule>

但是当我尝试击中它时，我得到了这个:

Error 310 (net::ERR_TOO_MANY_REDIRECTS): There were too many redirects.

Answer 1

尝试设置端口条件:

<rule>
    <condition type="scheme" operator="notequal">https</condition>
    <condition name="host" operator="equal">ELB-DNS</condition>
    <condition name="port" operator="equal">(80|443)</condition>
    <from>^/(.*)</from>
    <to type="permanent-redirect">https://ELB-DNS:8080/$1</to>
</rule>
