[Solved] Simple regex proxy routing not working as expected

Added by alevinetx almost 5 years ago

I have a very simple configuration that is almost identical to one listed as "working" in another forum post.
Post: https://redmine.lighttpd.net/boards/2/topics/8321

In my paste, I have provided my configuration, execution, and the execution log.
Paste: https://pastebin.com/b0q0b4ND

I have nc running on another session, and was getting successful connections without doing any attempts at changing the URL.

Regex: ^/redir-xyz/(.*)

The expectation is if I access :7890/redir-xyz/abc?123 that lighttpd will forward to :16201/abc?123
The result is that a match is initially found, and then the capture group (abc) fails to match.

The relevant configuration portion:

  $HTTP["url"] =~ "^/redir-xyz/(.*)" {
    url.rewrite-once = ( "^/redir-xyz/(.*)" => "/$1" )
    proxy.server = ( "" =>
                  (  "redir for xyz" =>
                      (
                         "host" => default.proxy.server.host,
                         "port" => "16201",
                      )
                   )
               )
}

I'm quite confused at this point, and gladly appreciate any guidance.

Thank you!

After the rewrite, the conditions are all matched afresh, and will not match ^/redir-xyz.

Please see proxy.header options to rewrite the proxied URL instead of using mod_rewrite. Docs_ModProxy

Thank you, that's what I was looking for.

I did see the proxy.headers, but I interpreted "host and URL paths in proxied HTTP headers" to mean "[header]: ...", and not the include the GET path, too., so I did not dig deeper on using that. A simple reword may help future clueless people like myself. :)

something like:

-> ... of proxied HTTP URL paths and host headers

Thank you again for your quick assistance!
