SMART on FHIR apps for Information exchange (Apache config.)

I reached out to Gary Monger yesterday and asked him how he configured Apache for his SMART on FHIR demo?
Gary's response was for me to post my question on the Developer Community forum - so that other people can benefit from the answer.

This is what I asked Gary:

I'm after turning a local Health Share instance on my laptop into a SMART on FHIR server.

The *recording about doing all of this is excellent, however, I could do with some instructions on how you configured the Apache web server before running the Cache scripts.

Therefore, before I put lots of effort into trying to figure out how to configure the web services before running the COS scripts - could you please give me any hints or tips before I attempt the install.

I'm running this version of HS:

Cache for Windows (x86-64) 2017.2.1 (Build 801U) Wed Dec 6 2017 09:07:51 EST [HealthShare Modules:Core:16.0.7241 + Linkage Engine:16.0.7241 + Patient Index:16.0.7241 + Provider Directory:15.0.7241 + Clinical Viewer:16.0.7241 + Active Analytics:16.0.7241]

I have already run the HS demo script:


do ##class(HS.Util.Installer).InstallDemo()

Plus the script that sets up the FHIR production:

zn "HSLIB"
do ##class(HS.Util.Installer).InstallFHIRServer("FHIRSERVER")

However, because of the unknowns as far as configuring the SSL stuff in Apache - I've held off running the rest of the COS code that you ran to install the rest of the software.

I have a Oracle Virtual Box VM environment that I can run openssl commands in - and my plan is to run these openssl commands to create the certs.
I've run these openssl commands in the past - and I'm hoping the openssl commands are similar to what you ran to configure your laptop before doing the recording.

openssl genrsa -out key.pem​
openssl req -new -key key.pem -out csr.pem
openssl x509 -req -days 9999 -in csr.pem -signkey key.pem -out cert.pem

I've also been told by that the server name in the certificate needs to match the server name - otherwise it won't work!

If you wouldn't mind sending me a copy of your stand alone csp app source code that you demonstrated in your recording - then that would be great as well.

Can you also tell me if Cache can be configured to support SMART backend-services?

Many Thanks,
-- Paul.

There are many ways to setup apache, and what works for your situation may vary.  My used a single instance of HealthShare, and two SMART applications that were hosted locally and served via CSP applications defined on my HealthShare instance.  I was running on Windows.

I used binaries from ApacheHaus,

Download here - .

Unzip and read the readme. 

Download the c++ runtime

Install, restart

Test apache installation http://localhost

Generate certificates.  I did this from HealthShare, but you can do it with openSSL, or other tools.

Configure the httpd.conf – change the server root, load the CSP modules, define the csp alias, create location entries, and create directory entries.  I’ll attach the conf file I used.

Configure the httpd-ahssl.conf – load webserver cert and key, and CA cert.  I’ll attached the file I used.

Configure CSP.ini to connect to HealthShare instance, need to make sure superserver port is correct, and username and password for the CSPService.  I just pasted in the encoded string from CSP.ini from the private webserver configuration

Run apache as a service. From bin directory in Apache:  httpd.exe -k install [-n “ServiceName”]

 I recommend starting without SSL, so comment out the #include of httpd-ahssl.conf in the httpd.conf file. Test, then put the SSL back in and test.

For the SMART apps:

I setup /csp applications one for each application.  You may want to do something different depending on your situation and the applications you are using.

Test that the web server routes to the apps.

You do need to have the common name in the cert match the host name.

My demo used SMART applications that I downloaded from  I created csp application definitions to launch the SMART apps I had downloaded.

I guess Cache could fill a few different roles in back end services.  I'll get back to you on that.


This is the main Apache HTTP server configuration file. It contains the

configuration directives that give the server its instructions.

Dynamic Shared Object (DSO) Support


To be able to use the functionality of a module which was built as a DSO you

have to place corresponding `LoadModule' lines at this location so the

directives contained in it are actually available before they are used.

Statically compiled modules (those listed by `httpd -l') do not need

to be loaded here.

SSL Demo Configuration for Apache Haus Distribution

FileName: conf/extras/mod_ahssl.conf


This is the Apache server configuration file providing SNI support.

It contains the configuration directives to instruct the server how to

serve pages over an https connection. For detailed information about these

directives see <URL:>

Do NOT simply read the instructions in here without understanding

what they do. They're here only as hints or reminders. If you are unsure

consult the online docs. You have been warned.


Required modules: mod_log_config, mod_setenvif, mod_ssl,

socache_shmcb_module (for default value of SSLSessionCache)

Listen 443 https


SSL Global Context


All SSL configuration in this context applies both to

the main server and all SSL-enabled virtual hosts.


SSL Protocols:

List the protocols that the client is permitted to negotiate.

See the mod_ssl documentation for a complete list.

SSLProtocol -all +TLSv1 +TLSv1.1 +TLSv1.2

SSL Cipher Suite:

List the ciphers that the client is permitted to negotiate.

See the mod_ssl documentation for a complete list.


SSL Honer Cipher Suite Order:

Forces the order of allowed cipher suites to the order above.

See the mod_ssl documentation for a complete list.

SSLHonorCipherOrder On

Pass Phrase Dialog:

Configure the pass phrase gathering process.

The filtering dialog program (`builtin' is a internal

terminal dialog) has to provide the pass phrase on stdout.

SSLPassPhraseDialog builtin

Inter-Process Session Cache:

Configure the SSL Session Cache: First the mechanism

to use and second the expiring timeout (in seconds).

SSLSessionCache "dbm:${SRVROOT}/logs/ssl_scache"

SSLSessionCache "shmcb:${SRVROOT}/logs/ssl_scache(512000)"
SSLSessionCacheTimeout 300


Some MIME-types for downloading Certificates and CRLs

AddType application/x-x509-ca-cert .crt
AddType application/x-pkcs7-crl .crl

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

SSLOptions +StdEnvVars

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 sent or allowed to be 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 [2-5]" \
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.
