Creating the /Webserver tree

The /Webserver ODB tree is created automatically when the mhttpd program is first run.

Purpose

The /Webserver ODB tree configures the behaviour and security features of mhttpd.


Examples

When initially created, the /Webserver tree contains the following keys:

[local:dev_expt:S]/WebServer>ls -lrt

Keys in /Webserver tree

Enable localhost port

  • Type: BOOL
  • Default: y

This key in the /Webserver tree tells mhttpd whether to bind to a port on localhost. The port to bind to is specified by the localhost port key.

localhost port

  • Type: INT
  • Default: 8080

This key in the /Webserver tree tells mhttpd which port to bind to on localhost (if Enable localhost port is true). If there are multiple experiments running on the same machine, each experiment should specify a different port.

localhost port passwords

  • Type: BOOL
  • Default: n

This key in the /Webserver tree tells mhttpd whether localhost connections require a password. See Create a password file in the mhttpd documentation for details on how to define the usernames/passwords.


Enable insecure port

  • Type: BOOL
  • Default: n

This key in the /Webserver tree tells mhttpd whether to allow http connections from other machines. The port to bind to is specified by the insecure port key.

insecure port

  • Type: INT
  • Default: 8081

This key in the /Webserver tree tells mhttpd which port to allow http connections on (if Enable insecure port is true). If there are multiple experiments running on the same machine, each experiment should specify a different port.

insecure port passwords

  • Type: BOOL
  • Default: y

This key in the /Webserver tree tells mhttpd whether http connections require a password. See Create a password file in the mhttpd documentation for details on how to define the usernames/passwords.

insecure port host list

  • Type: BOOL
  • Default: y

This key in the /Webserver tree tells mhttpd whether to only allow http connections from certain machines. The list of allowed machines is specified by the Host list key. Setting this to n allows http connections from any machine.


Enable https port

  • Type: BOOL
  • Default: n

This key in the /Webserver tree tells mhttpd whether to allow https connections from other machines. The port to bind to is specified by the https port key.

https port

  • Type: INT
  • Default: 8443

This key in the /Webserver tree tells mhttpd which port to allow https connections on (if Enable https port is true). If there are multiple experiments running on the same machine, each experiment should specify a different port.

https port passwords

  • Type: BOOL
  • Default: y

This key in the /Webserver tree tells mhttpd whether https connections require a password. See Create a password file in the mhttpd documentation for details on how to define the usernames/passwords.

https port host list

  • Type: BOOL
  • Default: n

This key in the /Webserver tree tells mhttpd whether to only allow https connections from certain machines. The list of allowed machines is specified by the Host list key. Setting this to n allows https connections from any machine.

Host list

  • Type: Array of STRING
  • Default: 10 elements, first entry set to localhost, all others empty.

This key in the /Webserver tree tells mhttpd which machines to allow connections from, if insecure port host list and/or https port host list are true. Specify one acceptable hostname per entry. You may increase the array length if you need to specify more that 10 hostnames.

Enable IPv6

  • Type: BOOL
  • Default: y

This key in the /Webserver tree tells mhttpd whether to allow connections via IPv6 as well as IPv4.

Proxy

  • Type: DIR

This key in the /Webserver tree configures mhttpd as a proxy to other http servers.

For each server you want to proxy to, add a STRING key to the /Webserver/Proxy directory. The key is the proxy name and the value is the server address to proxy to. The URL to access the proxy is http://<your_hostname>:<your_port>/proxy/<key_name>.

By default, one entry is included with a key of example, and a value that is an invalid URL (#http://localhost:8080). If you changed this to a valid URL, you could access it at http://<your_hostname>:<your_port>/proxy/example.

If your server was running on port 8080 and you set up a proxy to port 7000, then http://localhost:8080/proxy/example/foo/bar/baz would proxy to http://localhost:7000/foo/bar/baz

mime.types

  • Type: DIR

This directory tells mhttpd which MIME type to use for different file extensions. You may add more file types if desired, but most users will not need to touch this directory. Each entry in this directory is a STRING, where the key specifies the file extension (in upper case with a preceeding period, e.g. .PNG) and the value is the MIME type to use (e.g. image/png). MIME types tell web browsers what to do with different file types.
