[quote=19340:@Eric Brown]Does anybody have any experience in configuring a ProxyPass setup w/ Apache for use with the Standalone version (for SSL purposes)? I’ve tried variations of things such as this:
http://serverfault.com/questions/331161/how-to-configure-apache-to-act-as-an-ssl-proxy-to-an-application-server
Every time I use this or some other very similar setup, I get the following page when accessing my application:
Launching...
The application has gone off-line. Please try again later.
This application has encountered an error and cannot continue.
...
Getting frustrated, as I’ve spent nearly 12+ hours missing with a solution. Thanks![/quote]
Most of my apache configuration is from version 2.2 and few things has changed on version 2.4. So I can only show you an example based on Apache version 2.2. If you need to proxy a web site running in ssl mode you need to have “SSLEngine on” see: https://httpd.apache.org/docs/current/mod/mod_ssl.html#sslengine
This is one of my configurations files from a apache server version 2.2 running behind a Firewall in a DMZ environment. The IP address and some file locations has been changed for security reason.
I hope this can get you into the right direction.

SSL Engine Switch:
Enable/Disable SSL for this virtual host.
SSLEngine on
SSL Cipher Suite:
List the ciphers that the client is permitted to negotiate.
See the mod_ssl documentation for a complete list.
SSLCipherSuite HIGH:MEDIUM:!ADH
Server Certificate:
Point SSLCertificateFile at a PEM encoded certificate. If
the certificate is encrypted, then you will be prompted for a
pass phrase. Note that a kill -HUP will prompt again. Keep
in mind that if you have both an RSA and a DSA certificate you
can configure both in parallel (to also allow the use of DSA
ciphers, etc.)
SSLCertificateFile “/WEBSITES/APACHE/conf/server.crt”
Server Private Key:
If the key is not combined with the certificate, use this
directive to point at the key file. Keep in mind that if
you’ve both a RSA and a DSA private key you can configure
both in parallel (to also allow the use of DSA ciphers, etc.)
SSLCertificateKeyFile “/WEBSITES/APACHE/conf/server.key”
Server Certificate Chain:
Point SSLCertificateChainFile at a file containing the
concatenation of PEM encoded CA certificates which form the
certificate chain for the server certificate. Alternatively
the referenced file can be the same as SSLCertificateFile
when the CA certificates are directly appended to the server
certificate for convinience.
SSLCertificateChainFile “/WEBSITES/APACHE/conf/server-ca.crt”
Certificate Authority (CA):
Set the CA certificate verification path where to find CA
certificates for client authentication or alternatively one
huge file containing all of them (file must be PEM encoded)
Note: Inside SSLCACertificatePath you need hash symlinks
to point to the certificate files. Use the provided
Makefile to update the hash symlinks after changes.
#SSLCACertificatePath “/WEBSITES/APACHE/conf/ssl.crt”
#SSLCACertificateFile “/WEBSITES/APACHE/conf/ssl.crt/ca-bundle.crt”
Certificate Revocation Lists (CRL):
Set the CA revocation path where to find CA CRLs for client
authentication or alternatively one huge file containing all
of them (file must be PEM encoded)
Note: Inside SSLCARevocationPath you need hash symlinks
to point to the certificate files. Use the provided
Makefile to update the hash symlinks after changes.
#SSLCARevocationPath “/WEBSITES/APACHE/conf/ssl.crl”
#SSLCARevocationFile “/WEBSITES/APACHE/conf/ssl.crl/ca-bundle.crl”
Client Authentication (Type):
Client certificate verification type and depth. Types are
none, optional, require and optional_no_ca. Depth is a
number which specifies how deeply to verify the certificate
issuer chain before deciding the certificate is not valid.
#SSLVerifyClient require
#SSLVerifyDepth 10
Access Control:
With SSLRequire you can do per-directory access control based
on arbitrary complex boolean expressions containing server
variable checks and other lookup directives. The syntax is a
mixture between C and Perl. See the mod_ssl documentation
for more details.
#
#SSLRequire ( %{SSL_CIPHER} !~ m/^(EXP|NULL)/ \
and %{SSL_CLIENT_S_DN_O} eq “Snake Oil, Ltd.” \
and %{SSL_CLIENT_S_DN_OU} in {“Staff”, “CA”, “Dev”} \
and %{TIME_WDAY} >= 1 and %{TIME_WDAY} <= 5 \
and %{TIME_HOUR} >= 8 and %{TIME_HOUR} <= 20 ) \
or %{REMOTE_ADDR} =~ m/^192\.76\.162\.[0-9]+$/
#
SSL Engine Options:
Set various options for the SSL engine.
o FakeBasicAuth:
Translate the client X.509 into a Basic Authorisation. This means that
the standard Auth/DBMAuth methods can be used for access control. The
user name is the `one line’ version of the client’s X.509 certificate.
Note that no password is obtained from the user. Every entry in the user
file needs this password: `xxj31ZMTZzkVA’.
o ExportCertData:
This exports two additional environment variables: SSL_CLIENT_CERT and
SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
server (always existing) and the client (only existing when client
authentication is used). This can be used to import the certificates
into CGI scripts.
o StdEnvVars:
This exports the standard SSL/TLS related `SSL_*’ environment variables.
Per default this exportation is switched off for performance reasons,
because the extraction step is an expensive operation and is usually
useless for serving static content. So one usually enables the
exportation for CGI and SSI requests only.
o StrictRequire:
This denies access when “SSLRequireSSL” or “SSLRequire” applied even
under a “Satisfy any” situation, i.e. when it applies access is denied
and no other module can change it.
o OptRenegotiate:
This enables optimized SSL connection renegotiation handling when SSL
directives are used in per-directory context.
#SSLOptions +FakeBasicAuth +ExportCertData +StrictRequire
<FilesMatch “\.(cgi|shtml|phtml|php)$”>
SSLOptions +StdEnvVars
<Directory “/WEBSITES/APACHE/cgi-bin”>
SSLOptions +StdEnvVars
SSL Protocol Adjustments:
The safe and default but still SSL/TLS standard compliant shutdown
approach is that mod_ssl sends the close notify alert but doesn’t wait for
the close notify alert from client. When you need a different shutdown
approach you can use one of the following variables:
o ssl-unclean-shutdown:
This forces an unclean shutdown when the connection is closed, i.e. no
SSL close notify alert is send or allowed to received. This violates
the SSL/TLS standard but is needed for some brain-dead browsers. Use
this when you receive I/O errors because of the standard approach where
mod_ssl sends the close notify alert.
o ssl-accurate-shutdown:
This forces an accurate shutdown when the connection is closed, i.e. a
SSL close notify alert is send and mod_ssl waits for the close notify
alert of the client. This is 100% SSL/TLS standard compliant, but in
practice often causes hanging connections with brain-dead browsers. Use
this only for browsers where you know that their SSL implementation
works correctly.
Notice: Most problems of broken clients are also related to the HTTP
keep-alive facility, so you usually additionally want to disable
keep-alive for those clients, too. Use variable “nokeepalive” for this.
Similarly, one has to force some clients to use HTTP/1.0 to workaround
their broken HTTP/1.1 implementation. Use variables “downgrade-1.0” and
“force-response-1.0” for this.
BrowserMatch “.MSIE.” \
nokeepalive ssl-unclean-shutdown \
downgrade-1.0 force-response-1.0
Per-Server Logging:
The home of a custom SSL log file. Use this when you want a
compact non-error SSL logfile on a virtual host basis.
#CustomLog “/WEBSITES/APACHE/logs/ssl_request_log” \
“%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x “%r” %b”
