Using IIS 7.5 with URL Rewrite and Symfony

The IIS URL Rewrite 2.0 is IIS module that promises to do what the mod_rewrite does for Apache.

Download the URL Rewrite module from http://www.iis.net/download/urlrewrite .

Installation

Install the rewrite_2.0_rtw_x32.msi (or rewrite_2.0_rtw_x64.msi if you´re using a 64bit OS).

Check the the fastcgi is properly configured in your php.ini. This is not part of the installation of the URL Rewrite module but I had to do it because I changed from PHP 5.3 to 5.2 (due to the reasons explained at http://tecnofuenteabierta.blogspot.com/2010/12/running-symfony-14-with-ms-sql-server.html ).

cgi.force_redirect=0

fastcgi.impersonate=1

fastcgi.logging=0

extension_dir = "C:\PHP\ext"

extension=php_pdo.dll

Importing the Rules

Next thing you need is to import the rules from the .htaccess file.

Open the Internet Information Services (IIS) Manager on the left pane click on your site (for details on how to configure IIS for Symfony take a look at [2]) and you´ll see an icon URL Rewrite

Double click on the URL Rewrite icon. On the left pane named Actions click on Import Rules…

Select the .htaccess file on your web folder and click Import. Click on Apply.

Click on Back to Rules… and you´ll see the rules imported.

What this does is write a web.config file on your web folder than contains the rules for the URL Rewrite module and other fun thing Microsoft deems important.

Note: If you´re using rsync to update your site with –delete option be sure to copy the web.config file otherwise it will delete every time you update with rsync.

rsync -avr --delete --exclude-from=‘ path/exclude.txt‘ source/dir target/dir

Making IIS 7 serve MrSID Files

Until IIS 6 in order to serve MrSID files all you had to do was assign the proper NTFS permissions to the folder where the files were located and create a virtual directory in IIS. If you only do that and try to access a URL to an MrSID file on II 7 you´ll get a “404 - File or directory not found.” . The error message is confusing since the directory does exist. Finally figured there where restrictions with the MIME type, it seems IIS 7 only serves MIME you specifically declared.

To declare a new MIME type for MrSID you have to add an additional step.

1. Open the IIS Manager

2. Click on the virtual directory or directory

3. Click on MIME Types

4. Click on Add…

5. Fill the File name extension as .sid and the MIME type as application/octet-stream

6. Click Ok.

Now you should be able to access your MrSID via an URL.
