Pretty Permalinks for Multiple Wordpress blogs in sub folders on Windows Hosting with IIS
BY webmaster

We recently had a customer who had Windows Hosting with IIS and she had two WordPress blogs hosted on two subdirectories on the same hosting space. Windows hosting should be the last thing that should come to your mind when you want to do WordPress hosting as it will never come close to LAMP (Linux, Apache, MySQL, PHP) functionalities. Now the problem was that she could not set up Permalinks on both blogs. There was an already published solution on how to setup Permalinks in Wordpress on IIS but we had to tweak that a little to get it working in this scenario. The original solution involved the use ofcustom 404 files to handle Permalinks. Since permalinks are not actual pages they will always trigger a 404 error on an IIS server. Now by assigning our own php file to handle this error we can easily parse the URL requested and pass it on to index.php to simulate url-rewrites.

The solution presented in the above site allowed for a single wordpress installation. Here we had two wordpress installations in two sub directories. The solution was to process the request and identify the installation corresponding to which the request was made based on the sub-folder name. Once this was done all we had to do was change directories (for the case where it was needed) and then include the corresponding index.php. We had to chdir because otherwise the working directory would have been the directory where the 404 handler file is located and this could only work for a single installation.

The code used is given below. Copy this and modify for your needs when you have multiple wordpress installations under a domain in IIS and you want Pretty Permalinks for all of them
$_SERVER['REQUEST_URI'] = substr($_SERVER['QUERY_STRING'], strpos($_SERVER['QUERY_STRING'], ':80')+3);
if(stristr($_SERVER['QUERY_STRING'], '/blog/'))
elseif (stristr($_SERVER['QUERY_STRING'], '/books/'))

I came here via google.. Im so happy to see Zyxware publishing articles :)

I have a wp installation in the root and just installed another one in a subdir.
So, both these pages exist :

My problem is that when is requested, it's being redirected to as the default mod_rewrite rules check only the last part "about" and redirect to the main install.

Anoop chetta, do you know the regex for fixing this in htaccess ? I tried a lot of patterns . . no avail

Also, it may work if we set to parse .htaccess from each subdirectory where it exists and not just from the root ? Is that possible ?

Can you please post the rewrite rule and a simple regex match on new-wp-install\/about should do the trick. Anoop John

Hi guys

Yesterday I had to install a second WP installation on the same IIS shared hosting account. But that's not all...

It was a double WP install, on the same hosting account, using 2 different domains, on one of them the blog is not even served from the "real" hosting path, and where both supposed to use pretty permalinks.

If this is not already a WP-routing nightmare, it was all had to be done under a Windows hosting environment - and this actually posed the biggest hurdle!

Installing Apache-like mod_rewrite ISAPI's is out of the question on a shared host, so I was left with the dreaded single error page for the entire account. And I'm sure no PHP wiz...

And here is where your script helped me, in guiding me in the right path. After a some tinkering with your code, the host's domain-pointing and URL redirection, and WP own redirect, it all now plays nicely, thank god... and you!

So all the best and keep posting your coding tips - you may never know when it will save someone from the other side of the world.

Permalinks are necessary for every engine will not be able to understand the content much


I read this comment and I think that Permalinks are necessary for every word press.because search engine will not understand the content very much. This is good topic and try to find out this problem as possible as.

This worked great for me. I wanted to use a separate wordpress installation in a sub folder as I am not 100% confident in the wp-ecommerce solution and I did not want to break my main site while I figured it all out. Permalinks are a requirement for me and so is using IIS. Even though Apache may be better, I currently have a working IIS server to play with.

Thanks for taking the time to write this up, it worked great for me.
