Apache reverse proxy setup with subpath (http://myhost.xx/searx)

[return42]

I have setup searx as uwsgi service at http = 127.0.0.1:8888 and a apache mod_proxy with ProxyPath to a filtron service listening on 127.0.0.1:4004 (target is searx at port :8888).

The setup works fine when I use the root URL as public URL http://myhost.xx/:

ProxyPass "/" "http://127.0.0.1:4004/"
ProxyPassReverse "/" "http://127.0.0.1:4004/"

Now I want to move my searx instance to a subpath in the public URL, e.g. http://myhost.xx/searx:

ProxyPass "/searx" "http://127.0.0.1:4004/"
ProxyPassReverse "/searx" "http://127.0.0.1:4004/"

With I got a pure "HTML page" which tries to load resource relative from root URL / instead from /searx/

I read this article https://blog.macuyiko.com/post/2016/fixing-flask-url_for-when-behind-mod_proxy.html and I found similar in our sources 6ef7c32 so I tried also:

ProxyPass "/searx" "http://127.0.0.1:4004/"
ProxyPassReverse "/searx" "http://myhost.xx/searx"

But this does not change anything, the HTML page from searx always try to load resources from the root URL. .. where is my mistake?

Why would you want to do that? I mean nowadays SSL/TLS certificates are free even for subdomains. There is no real reason to serve another service in a subpath.

@unixfox sorry if I was not clear I was asking about ProxyPass and subpath .. I have found my mistake and will post the solution ..

I forgot to set request header X-Script-Name here is my final apache site

Updated: Jan, 31 2020 ...

ProxyPreserveHost On

<Location /searx >

    Require all granted
    Order deny,allow
    Deny from all
    #Allow from fd00::/8 192.168.0.0/16 fe80::/10 127.0.0.0/8 ::1
    Allow from all

    ProxyPass http://127.0.0.1:4004
    RequestHeader set X-Script-Name /searx

    # In Apache it seems, that setting HTTP_HOST header direct here does have no
    # effect.  I needed to set 'ProxyPreserveHost On' (see above).  HTTP_HOST is
    # needed by searx to render correct *Search URL* in the *Link* box and
    # *saved preference*.

    # RequestHeader set Host myhost.xx
