# Adding a Web Server to Your Sim
|
||
|
||
If Trick is [configured with Civetweb](Configure-Civetweb.md),
|
||
adding a web server to your simulation simply requires including the CivetServer sim module into your **S_define** file:
|
||
|
||
```
|
||
#include "sim_objects/CivetServer.sm"
|
||
```
|
||
|
||
## Configuration of the Web Server
|
||
|
||
The following (input.py) parameters are available to configure your web server:
|
||
|
||
|Parameter Name | Default Value | Description |
|
||
|---------------------------|---------------------------|-----------------------------------------------------------------|
|
||
|web.server.enable | False |Must be explicitly enabled |
|
||
|web.server.port | "8888" |Web servers “listen” port |
|
||
|web.server.document_root | "www" |Web servers document root |
|
||
|web.server.debug | False |Print Client/Server Communication. |
|
||
|web.server.ssl_enable | False |Encrypt traffic. Uses https instead of http. |
|
||
|web.server.path_to_ssl_cert|"~/.ssl/server.pem" |Path to your certificate. This is only used if ssl_enable = True|
|
||
|web.server.error_log_file | "civet_server_error.log" |CivetWeb error log file. |
|
||
|
||
For your web server to be active, you must at least specify the following :
|
||
|
||
```python
|
||
web.server.enable = True
|
||
|
||
```
|
||
|
||
To have your web server listen on port 8890, rather than 8888, you would specify:
|
||
|
||
```python
|
||
web.server.port = "8890"
|
||
```
|
||
|
||
To serve files from a directory called ```my_document_root```, rather than ```www```:
|
||
|
||
```python
|
||
web.server.document_root = "my_document_root"
|
||
```
|
||
|
||
To see client/server communication:
|
||
|
||
```python
|
||
web.server.debug = True
|
||
```
|
||
|
||
## When the Web Server Starts
|
||
The web server, if enabled, will start during sim initialization. When it does, it will look for the specified document root directory. By default that’s “www”. If root directory doesn’t exist, one will be created with a simple index.html file , a style sheet, and a couple of directories.
|
||
|
||
|
||
## Connecting to Your Web Server
|
||
Assuming that you accepted the default port, connect to ```http://localhost:8888/``` (```https://localhost:8888/``` if ssl_enable=True) from your web browser. This will display the index.html file in your root directory.
|
||
|
||
|
||
## The Default Document Root Directory
|
||
|
||
The default document root directory that was initially created for you is minimal.
|
||
|
||
```
|
||
www/
|
||
index.html
|
||
style.css
|
||
apps/
|
||
images/
|
||
```
|
||
|
||
**index.html** is the file that’s displayed when you connect to http://localhost:8888/.
|
||
|
||
**style.css** is a CSS style-sheet that’s included by index.html to give it some pizzazz.
|
||
|
||
The **apps** directory contains links to some example html/javascript applications
|
||
in ```$TRICK_HOME/trick_source/web/apps```.
|
||
|
||
The **images** directory contains trick_icon.png.
|
||
|
||
**You are encouraged to add to, modify, and/or delete these files and directories to best suite the needs of your project.**
