Create a file named web.config
in your web root and place the following into the file
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="Rewrite to index.php">
<match url="index.php|robots.txt|images|test.php" />
<action type="None" />
</rule>
<rule name="Rewrite CI Index">
<match url=".*" />
<conditions>
<add input="{REQUEST_FILENAME}" pattern="css|js|jpg|jpeg|png|gif|ico|htm|html" negate="true" />
</conditions>
<action type="Rewrite" url="index.php/{R:0}" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
The above is the example used on the Codeigniter Forums here.
You may also need to ensure that $config['uri_protocol']
is set to AUTO
