### IIS with ARR and URL Rewrite
<details>
<summary>click here to expand</summary>
**Disclaimer:** It might be possible that the config below is not working 100% correctly, yet. Improvements to it are very welcome!
**Please note:** Using IIS as a reverse proxy comes with some limitations:
- A maximum upload size of 4GiB, in the example configuration below the limit is set to 2GiB.
#### Prerequisites
1. **Windows Server** with IIS installed.
2. [**Application Request Routing (ARR)**](https://www.iis.net/downloads/microsoft/application-request-routing) and [**URL Rewrite**](https://www.iis.net/downloads/microsoft/url-rewrite) modules installed.
3. [**WebSocket Protocol**](https://learn.microsoft.com/en-us/iis/configuration/system.webserver/websocket) feature enabled.
For information on how to set up IIS as a reverse proxy please refer to [this](https://learn.microsoft.com/en-us/iis/extensions/url-rewrite-module/reverse-proxy-with-url-rewrite-v2-and-application-request-routing).
There are also information on how to use the IIS Manager [here](https://learn.microsoft.com/en-us/iis/).
The following configuration example assumes the following:
* A site has been created that is configured with HTTPS support and the desired host name.
* A server farm named `nc-server-farm` has been created and is pointing to the Nextcloud server.
* No global Rewrite Rules has been created for the `nc-server-farm` server farm.
Add the following `web.config` file to the root of the site you created as the reverse proxy.
```xml
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.web>
<!-- Allow all urls -->
<httpRuntime requestValidationMode="2.0" requestPathInvalidCharacters="" />
</system.web>
<system.webServer>
<rewrite>
<rules>
<!-- Force https -->
<rule name="Https" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTPS}" pattern="^OFF$" />
</conditions>
<action type="Redirect" url="https://{HTTP_HOST}/{REQUEST_URI}" appendQueryString="false" />
</rule>
<!-- Redirect to internal nextcloud server -->
<rule name="To nextcloud" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTPS}" pattern="^ON$" />
</conditions>
<action type="Rewrite" url="http://nc-server-farm:11000/{UNENCODED_URL}" appendQueryString="false" />
</rule>
</rules>
</rewrite>
<security>
<!-- Increase upload limit to 2GiB -->
<requestFiltering allowDoubleEscaping="true">
<requestLimits maxAllowedContentLength="2147483648" />
</requestFiltering>
</security>
</system.webServer>
</configuration>
```
