Suggest rewrite rules on IIS Network (Multisite)

[guy_fr]

Server: Microsoft IIS - 8
Wordpress: 3.5.1 (multisite)

On subfolder install, suggest for web.config is:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="WordPress Rule 1" stopProcessing="true">
                    <match url="^index\.php$" ignoreCase="false" />
                    <action type="None" />
                </rule>
                <rule name="WordPress Rule for Files" stopProcessing="true">
                    <match url="^([_0-9a-zA-Z-]+/)?files/(.+)" ignoreCase="false" />
                    <action type="Rewrite" url="wp-includes/ms-files.php?file={R:1}" appendQueryString="false" />
                </rule>
                <rule name="WordPress Rule 2" stopProcessing="true">
                    <match url="^([_0-9a-zA-Z-]+/)?wp-admin$" ignoreCase="false" />
                    <action type="Redirect" url="{R:1}wp-admin/" redirectType="Permanent" />
                </rule>
                <rule name="WordPress Rule 3" stopProcessing="true">
                    <match url="^" ignoreCase="false" />
                    <conditions logicalGrouping="MatchAny">
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" />
                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" />
                    </conditions>
                    <action type="None" />
                </rule>
                <rule name="WordPress Rule 4" stopProcessing="true">
                    <match url="^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*)" ignoreCase="false" />
                    <action type="Rewrite" url="{R:1}" />
                </rule>
                <rule name="WordPress Rule 5" stopProcessing="true">
                    <match url="^([_0-9a-zA-Z-]+/)?([_0-9a-zA-Z-]+/)?(.*\.php)$" ignoreCase="false" />
                    <action type="Rewrite" url="{R:2}" />
                </rule>
                <rule name="WordPress Rule 6" stopProcessing="true">
                    <match url="." ignoreCase="false" />
                    <action type="Rewrite" url="index.php" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>		

On sudomain install, it is:

<?xml version="1.0" encoding="UTF-8"?>

                    <action type="None" />
                </rule>
                <rule name="WordPress Rule for Files" stopProcessing="true">
                    <match url="^files/(.+)" ignoreCase="false" />
                    <action type="Rewrite" url="wp-includes/ms-files.php?file={R:1}" appendQueryString="false" />
                </rule>
                <rule name="WordPress Rule 2" stopProcessing="true">
                    <match url="^wp-admin$" ignoreCase="false" />
                    <action type="Redirect" url="wp-admin/" redirectType="Permanent" />
                </rule>
                <rule name="WordPress Rule 3" stopProcessing="true">
                    <match url="^" ignoreCase="false" />
                    <conditions logicalGrouping="MatchAny">
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" />
                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" />
                    </conditions>
                    <action type="None" />
                </rule>
                <rule name="WordPress Rule 4" stopProcessing="true">
                    <match url="^(wp-(content|admin|includes).*)" ignoreCase="false" />
                    <action type="Rewrite" url="{R:1}" />
                </rule>

                    <action type="Rewrite" url="{R:2}" />
                </rule>
                <rule name="WordPress Rule 6" stopProcessing="true">

                    <action type="Rewrite" url="index.php" />

I think that Wordpress Rules for files and Wordpress Rule 4 and 5 should follow same rules than htaccess suggest.
When following actual suggest in a subfolder installation, I get an HTPP Error in call to sub site, error is always reproductible for me - can you confirm.

A fix could be to add a subdir replacement rule {R:1} for subdomain install and {R:2} for subfolder.

Implementation in the network.php file (adding $iis_subdir_replacement_12):

$iis_subdir_replacement = $subdomain_install ? '' : '{R:1}';
$iis_subdir_replacement_12 = $subdomain_install ? '{R:1}' : '{R:2}';

$web_config_file = '<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>

                    <match url="^index\.php$" ignoreCase="false" />
                    <action type="None" />
                </rule>';
				if ( is_multisite() && get_site_option( 'ms_files_rewriting' ) ) {
					$web_config_file .= '

Sorry for my english :)

Does this also work in an Azure Web Site? ​http://www.windowsazure.com/en-us/develop/php/tutorials/website-from-gallery/

[spencercameron]

@dvmorris, yes. They seem to work on Azure. I just tried them on a multisite install on an Azure Website. A cursory glance looks fine.

[dvmorris]

You're right, I ended up getting them to work as well. My main issue was not having ms_files_rewriting flag set for the blog. I don't think there is a place to edit that flag in the GUI, so I had to do it directly in the database.

Also, it looks like ms-files.php is hardcoded to pull files from blogs.dir, is that correct?

Could someone supply a patch? It would make it easier to see what is being changed.

ms_files_rewriting is set to false (0) for new networks (post 3.5) — you shouldn't have it set, because ms-files.php is no longer used for uploads. FYI.

I suggest closing this ticket as a duplicate in favour of the following tickets due to testing and/or patches already added.

#24963 IIS Sub-Directory install
#25106 IIS Sub-domain install

Closing as duplicate of both #25106 and #24963.
