Added ability to cache specified HTTP headers.

[mlucas99]

Great library, saves a ton of work. Don't know if this is something you're interested in adding but it was a necessity for one of our latest projects.

When a response was cached, it didn't send any of the custom headers we were using to hold the total row count, and the Link header we were using to send pagination links. So I added an OutputCacheAttribute parameter that will preserve headers you specify.

Ex.
[CacheOutput(ClientTimeSpan = 60, ServerTimeSpan = 60, HeadersToInclude = "X-Total,Link")]

thanks, this is a good idea, let me wrap my head around this

A bug just cropped up in that code that could cause a 500, so you don't want this code as is. I had duplicated the line AddCachedHeaders call on line 164.

Any update on this functionalty? It seems promising

Is this something that will be added? This PR is the only thing stopping us from using this LIB.

I ended up forking the project and using @mlucas99 changes... The only additional change is that on line 100 ShortTime requires an additional 3rd paramenter.

CacheTimeQuery = new ShortTime(ServerTimeSpan, ClientTimeSpan, null);

Thanks!

Hi, Any update on this? I would love to cache custom headers too for some requets
thanks

[mribichich]

Sorry to bother, is this still a possibility? Do you need any help? thanks!

[mribichich]

@mlucas99 could you update the PR to the latest version of CacheOutputAttribute.cs
Or I could copy the new changes and make a new PR
let me know

I've been using this and it works great

thanks!

[mribichich]

@filipw Could you merge this? Because I think that mlucas is not using it anymore

let me know if you want me to do it

thanks!

I couldn't get this to work with this version, so I updated the code and made the modifications needed to allow for custom headers to be cached.
