Remember that whatever solution you use to "ping" your site you should specify the Keepalive.aspx page.  In that way the transaction's data transfer is kept to a minimum and it accomplishes the purpose of keeping the site loaded.

Also remember that the issue of timing out the application and removing it from memory comes from the ASP.Net architecture.  Anything done at the DNN level will only add complexity and more opportunity for problems.  Using a ping or keepalive solution has worked great for me for years, and I run several versions of DNN concurrently on my server, including 1.0.10e.  All come up really fast.  IIS compression is the other big feature for overall performance improvement.

Carlos - that is a really good point.

If you look at the config section of pagemonkey will notice that you can specify the URL to "ping" therefore you can set it to use the keepalive.aspx page and not the default.aspx page by explicitly targeting that page.

My sample web.config snippet in the pagemonkey download had pointed to default.aspx - I have since changed them to point to keepalive.aspx.

I have found that you also need to request other pages to keep everything loaded and fast.

If you only use the KeepAlive.aspx page then you will notice that some other pages still take some time to load as their individual folders are Just In Time compiled.

This is especially true on the larger modules that have several user controls. I notice it most on the Catalook Store, and Active Forums.

As an enhancement to Pagemonkey I will be adding the ability to configure sub-folders you wish to have pre-compiled as part of PageMonkey's "alive" mode.

When you forcably load a user control I believe it triggers the recompile at that time.

LoadControl(mycontrol.ascx) - I think for asax files you need to simply request them programmatically to precompile them.

That would most likely do the trick for keeping modules like catalook and activeforums fresh.

I'm thinking you would NOT want to simply process ALL ascx pages in a DNN install this way.

That might have unwanted side effects no?

Thanks for many good suggestions... but is there absolutely no way to tell IIS *not* to recycle? Am I being naive by thinking there's some kind of setting in IIS/.NET/elsewhere that controls that?
