mod_proxy ProxyPassReverse incorrectly adjusting Location header in redirect?
|[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]|
Hi, as an interim solution in an internal reorganization of server resources, I want to use mod_proxy as a reverse proxy to move the entire functionality of a public-facing server (www.example.com) to an internal server (internal.example.com). (configuration at end) https is used in this site only for logging in, after which a 302 redirect is issued pointing to http://www.example.com/home.html, and the session continues through http. I am having trouble getting ProxyPassReverse to rewrite the Location header in the redirect properly. Here's the sequence: -client sends POST login credentials to https://www.example.com/login.html -request is proxied by https://www.example.com to https://internal.example.com/login.html -login succeeds, respond with 302 redirect to http://internal.example.com/home.html -reply goes to https://www.example.com - ******** ProxyPassReverse rewrites the Location header from http://internal.example.com/home.html to https://www.example.com/home.html -reply received by client, which acts on the redirect The starred ******* step is what is going wrong, as the proxy is changing the http to https despite the explicit "ProxyPassReverse / http://internal.example.com" line. I have tried many different tweaks to the configuration, but I always find that the header is rewritten back to https despite my explicitly specifying http in the response. I feel like I must be misunderstanding something here. Can anyone help me untangle it?
