Will reinstalling URL Rewrite module cause something to break

Meh 1

Just recovered my VM from a fatal crash. Upon check IIS, the URL Rewrite module is no longer listed, but I've verified that the entries are still in the C:\Windows\System32\inetsrv\config\applicationHost.config file.

Will reinstalling the module have any undesirable effects?

Hi @Meh ,

Shouldn't the URL Rewrite rule be in your web.config file? you should check the web.config file in your project, not applicationhost.config.

ApplicationHost.config is the root file of the configuration system when you are using IIS 7 and above. It includes definitions of all sites, applications, virtual directories and application pools, as well as global defaults for the web server settings.

The location of web.config is C:\inetpub\wwwroot\web.config

I forgot to mention that it the VM is the ARR server. It forwards the requests to other servers downstream.

@Meh Even if you are using ARR server, your URL Rewrite Rule should also be in web.config. Did you check your web.config file?

The Default Web Site doesn't have a web.config. I'll just create a new one and move the rewrite rules to it. I guess doing this allows me to just move the file to a safe location, reinstall the module, and return the file without any problems, correct?

@Meh What you are looking for is the web.config under your current website. on which website your project is published, your rewrite rules should be created under that website. Normally, if the URL Rewrite module is no longer listed, then the web.config will not exist either, so your previous rule is lost. reinstalling the URL Rewrite module may cause the rule to be lost, If you are worried about losing your rule again, you can back up the web.config on that website.
