Example of an Apache HTTPD Configuration for Bitcoin JS Remote

[I am assuming a little knowledge about Apache httpd. You had better read on Apache httpd directives: http://httpd.apache.org/docs/2.2/mod/directives.html. Of course, this is only an example of many other configurations]

Assuming your bitcoin.conf file includes:

 rpcuser=myuser
 rpcpassword=mypass

First, generate a suitable file for Basic Authentification. See man htpasswd or execute

 htpasswd -b -c my_prefer_filename myuser mypass

Set following Apache directives in the proper context, i.e. server or virtual host configuration:

 <Proxy http://127.0.0.1:8332>
   AuthType Basic
   AuthName "Bitcoin Access"
   AuthUserFile my_prefer_filename
   Require user myuser
   Order deny,allow
   Allow from all
 </Proxy>

Assuming you want to access Bitcoin JS Remote with http://mydomain/jbc

 Alias /jbc pathabs_to_bitcoin-js-remote
 ProxyPass /lbc/ http://127.0.0.1:8332/
 # ProxyPassReverse is not required because bitcoind talks pure
 # JSON, i.e no HTTP Headers with URIs are generated by bitcoind
 # ProxyPassReverse /lbc/ http://127.0.0.1:8332/

Above ProxyPass directive is asuming you are set the RPC.url field to "/lbc/" into "settings.json" file, located in the bitcoin-js-remote directory. See the settings.json_sample file for proper syntax.

A variety of configurations are feasible:

 # If RPC.url is an absolute path (i.e. RPC.url : /lbc/),
 # bitcoind at 127.0.0.1 shall be accessed by http://mydomain/jbc/
 ProxyPass /lbc/ http://127.0.0.1:8332/
 #
 # If RPC.url is a relative path (i.e. RPC.url : lbc/),
 # bitcoind at 127.0.0.1 shall be accessed by http://mydomain/jbc/lbc/
 ProxyPass lbc/ http://127.0.0.1:8332/
 # 
 # Apache can also proxy your access to any other IP by
 # accessing to http://mydomain/jbc
 ProxyPass /lbc/ http://www.worldbank.org:8332/

Please, note you are *not* required to set into the settings.json file the pair rcpuser/rcppassword. The required header with Basic Authentication is automatically generated by Apache when proxing, thanks for the above Auth directives.

Set RPC.user=rcpuser and RPC.password=rcppassword in the settings.json file if you are not able to configure your Apache webser; for instance, people using hosting instead of virtual or dedicated server. But, please, keep in mind settings.json file can be read by everybody: http://mydomain/jbc/settings.json

That's all. Restart your Apache web server.

Other interesting Apache directives:

To redirect all HTTP to HTTPS (of course, you need a well-configured ssl site). !!! SSL access is extremely recommended to protect your Bitcoin data.

 RewriteCond %{HTTPS} off
 RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

To avoid your log file from flooding

 SetEnvIf Request_URI "^/jbc/" dontlog
 SetEnvIf Request_URI "^/lbc/" dontlog
 CustomLog myfile.log combined env=!dontlog

Finally, if you go in trouble, check proper access to bitcoin daemon with curl:

 curl --trace-time --trace-ascii - \
      --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getinfo", "params": [] }' \
      --header 'content-type: text/plain;'\
      http://myuser:mypass@127.0.0.1:8332/
