<p>When creating an HTTP listener, you can choose to enable the listening and forwarding function and specify the HTTPS port. ELB will forward the request received on the HTTP port to the specified HTTPS listener.</p> <p><strong><span style="font-size:18px">Overview</span></strong></p> <p>For HTTP listener of external ELB instances, you can choose to configure the URL forwarding policy. The monitoring redirection function is used to configure the HTTP listener to forward to the HTTPS listener, where the port for listening and forwarding can be customized. When the HTTP listener configures this option, ELB will forward the request received on the HTTP port to the specified HTTPS listener. It is often used to jump between HTTP requests and HTTPS requests in Web services, making it easy for you to deploy HTTPS across the site. ELB provides the HTTP redirect function in all regions.</p> <p>When creating an HTTP listener, you can choose to enable the listening and forwarding configuration. When HTTP specifies the target HTTPS listener, the dependency relationship is established and HTTPS cannot be released. If you need to release the HTTPS listener, you can choose to delete the HTTP listener and remove the dependency first.</p> <p><strong><span style="font-size:18px">Prerequisites</span></strong></p> <p>You have successfully created an HTTPS listener for external ELB to receive redirected requests.</p> <p><strong><span style="font-size:18px">Procedures</span></strong></p> <p>1.&nbsp;Log in to the ELB Console.</p> <p>2.&nbsp;In the left navigation pane, click <strong>Instance Management</strong> to enter the <strong>Instance Management</strong> page.</p> <p>3.&nbsp;Click the instance name of the target ELB instance and enter the <strong>Instance Information</strong> page.</p> <p>4.&nbsp;Click the <strong>Listener</strong> tab.</p> <p>5.&nbsp;In the upper-right corner of the tab, click <strong>Create</strong> to enter the <strong>Create Listener</strong> page.</p> <p>6.&nbsp;Configure the HTTP listener as described in the following tables.</p> <p><strong>Basic Information</strong></p> <table border="1" cellpadding="0" cellspacing="0" style="width:0px"> <tbody> <tr> <td style="background-color:#ededed; width:210px"> <p><strong>Configuration item</strong></p> </td> <td style="background-color:#ededed; vertical-align:top; width:557px"> <p><strong>Description</strong></p> </td> </tr> <tr> <td style="width:210px"> <p>Description</p> </td> <td style="vertical-align:top; width:557px"> <p>Customize the description of a listener.</p> </td> </tr> <tr> <td style="width:210px"> <p>Frontend protocol</p> </td> <td style="vertical-align:top; width:557px"> <p>Select HTTP as the frontend protocol.</p> </td> </tr> <tr> <td style="width:210px"> <p>Port</p> </td> <td style="vertical-align:top; width:557px"> <p>Enter the port number used to receive the request and forward the request to the server resource pool.</p> <p><strong>Note:</strong> In the same ELB instance, the listener port number cannot be repeated.</p> </td> </tr> <tr> <td style="width:210px"> <p>Listen forward</p> </td> <td style="vertical-align:top; width:557px"> <p>Turn on the Listen forward function.</p> </td> </tr> <tr> <td style="width:210px"> <p>Target listener</p> </td> <td style="vertical-align:top; width:557px"> <p>Select the target HTTPS listener as the forwarding object.</p> </td> </tr> </tbody> </table> <p>7.&nbsp;Click <strong>Next</strong> to confirm the configuration information.</p> <p>8.&nbsp;Click <strong>Create</strong>, and you will see an <strong>Operation succeeded</strong> message at the bottom of the page.</p> <p><strong><span style="font-size:18px">Result</span></strong></p> <p>On the listener tab, you can view the created HTTP forwarders.</p>
