Turns one needs to use a different syntax:

Re: [users@httpd] Newbie - Apache as internet facing proxy for Windows/IIS backend .net app server?

You could add additional authentication requirements in the reverse proxy
for specific requests. You can also make sure to only proxy requests that
match what you think the backend should process.
There are a lot of tools that can help you, but as you said, you might get
the best results if someone actually looks at your specific system and your
specific requirements.

Re: [users@httpd] Newbie - Apache as internet facing proxy for Windows/IIS backend .net app server?

[Charles Marcus]

Ok, a follow-up question...

My only concern here is security. This is not and never will be a
heavily used system, but it will serve as a gateway to a backend
accounting system, so I'm not concerned with load balancing or any of
the other features that come with a reverse proxy. My only concern is
that it be as secure as possible.

I know that a reverse proxy in and of itself doesn't add any real
security (other than this will be running on linux, which I'm more
comfortable exposing to the internet).

So, with that in mind... I would appreciate any links to how to do this
with security as the primary goal. Something more than just 'enable
mod_security'.

Also, I would be very open to paying a consultant to assist in setting
this up, if I can be convinced they are legit and worth their asking
price. Two things I'd want/need help with is testing to whittle down the
http features to only those necessary to interact with our system,
taking advantage of mod_secs 'continuous passive security assessment'
feature, and anything else that makes sense.

And thanks for the responses so far!

I think there are some quirks that make this a little unruly. But you
could extract it with a simple SetEnvIf in advance than look at the
set environment variable instead:

SetEnvIf Host ^([^.]+) HOST_UNQUALIFIED=$1

Then use reqenv('HOST_UNQUALIFIED') instead of the variable.

[users@httpd] Getting hostname from FQDN as variable in config file

[sebb]

Is it possible the access the hostname part of a FQDN in a config file?

For example, suppose the config has the following condition:



This might resolve to a directory such as:

/var/test/NAME.example.com

Is there a way to resolve just the initial part of the host, i.e. NAME?

[users@httpd] Security Headers, ISP, no root won't work

[i...@h-c-b.de]

Hi!

I want to enable some security headers. I don't have access to my =
vhosts, and not to the apache config, so I used my .htaccess.


Header set X-Frame-Options SAMEORIGIN
Header set X-XSS-Protection "1; mode=3Dblock"
Header set X-Content-Type-Options "nosniff"
Header always set Referrer-Policy "no-referrer"
Header set Content-Security-Policy "default-src 'self' ; =
referrer no-referrer ;"
Header unset X-Powered-By


According to my ISP there are the following directives:

apache2.config: AllowOverride none
vhosts  AllowOverride All

None of the above security headers are working. Any tips?

Thank you!
