WordPress + Multisite + IIS7, URL Rewrite bug with pagination and 'Older Entries' links causing 404

[sjlevy]

Using Multisite WordPress (3.3.2) on IIS7 with the standard URL Rewrite rules causes issues with trailing slashes and the pagination links

For example, if you visit a multisite blog with a URL like this: ​http://mydomain.com/bloga (without trailing slash) the 'Older Entries' link becomes ​http://mydomain.com/bloga/bloga/page/2/ -- it doubles up the blog slug in the URL causing a 404 error. Additionally any previous page link 1 2 3 4 5 etc have bad URL's as well.

If you visit ​http://mydomain.com/bloga/ (with trailing slash) the 'Older Entries' link is correctly ​http://mydomain.com/bloga/page/2/

I have found the issue to be present across multiple servers, with fresh, theme-less and plugin-less installations of WordPress

With fresh installations of WordPress

WordPress 3.4 too?

WordPress 3.4 too?

Oops forgot to mention, yes the problem persists after latest WP update

While the double blog name issue in pagination links is still a duplicate of #18034, the fact that redirect_canonical() is disabled for IIS makes it more prominent. Related: #20484

On Apache, mydomain.com/bloga is redirected to mydomain.com/bloga/.
