Contrib.Cache Module IIS Kernel Cache Profile

I recently enabled the maxAge setting inside the Contrib.Cache module for my site. All was going good until I tried to paginate on my blog posts page. IIS was not varying the cache by querystring so /blog?page=2 was returning my /blog content.

I looked in the OutputCacheFilter.cs file of Contrib.Cache and found that it is was varying by a bunch of different headers but not adding a profile for querystring.

I am going to try and adding the varyByQuerystring option in the Filter and was wondering if anyone else had experience with this or has added it and had success.

Are you sure you're using the latest version of Contrib.Cache?

Yes I am using version 1.1. What I was seeing was when I turned on the maxAge setting my pagination was not working. /blog page was being cached and there was no distinction between /blog?page=2. I opened up Contrib.Cache OutputCacheFilter.cs and added this line to the ApplyCacheControl method. 

response.Cache.VaryByParams["page"] = true;

This seems to have fixed the issue. My question was more, "has anybody else experienced this?". And is it expected when using maxAge right now?

Yes, we've experienced that on Vary by should probably be configurable.
