Apache2 ProxyPassReverse not rewriting URL properly

Question

I have the below apache virtualhost configuration. ProxyPassReverse does not appear to be converting the URLs properly.

URL http://www.example.com/9999pcap/ shows a directory listing on a remote device and the directory listing looks fine but if you click on a file captype1.pcap1.gz to download it you get

The requested URL /captype1.pcap1.gz was not found on this server

and the URL bar shows /captype1.pcap1.gz. If you manually change the URL to /9999pcap/captype1.pcap1.gz it properly downloads the file.

URL /9999/ shows the login page of a remote device but it looks wrong because it's not properly downloading style sheets and other files and attempting to login fails with

The requested URL /cgi-bin/luci/ was not found on this server.

Can anyone tell me what I'm doing wrong here? Thanks!

apache proxypassreverse ServerName not working

I gave up on this method as it doesn't work as it should. Simply manually substituting URL pieces works just fine as shown in this post.

<Location /9999pcap/>
        ProxyPass http://localhost:22003/
        ProxyPassReverse http://localhost:22003/
        Substitute s>href='/>href='/9999pcap/>
        SetOutputFilter INFLATE;SUBSTITUTE;DEFLATE
        RequestHeader unset Accept-Encoding
</Location>

Oh that hurts to look at. – Carl F. Dec 16 '14 at 13:42
FYI, the reason this doesn't work is normal http proxying doesn't modify the HTML (Your Substitute directive does that). If you want mod_proxy to do the work in and 'HTML aware way' you can use mod_proxy_html – Unbeliever Sep 07 '16 at 18:49
