I like Varnish's performance in caching and try to add a capability of preloading cached contents into Varnish server.<br>
<br>
My understanding is that I need to find a right spot for inserting hash index, and then right spot for inserting cached contents into cache storage.<br>

Why not just implement a simple HTTP client script to walk the list of URL's you want to load on some suitable interval? This way you don't need any code modifications.<div class="im"><br></div></blockquote><div>
This would work if I could pull the contents. Unfortunately, my cached contents can not be pulled in, can only be pushed in by an outside server. So my own program will receive the pushed-in contents in terms of http header and body, and then inserted them into the Varnish cache storage.</div>

I also intend to use memory as only cache storage, not hard disk.<br>

Simply define the storage file/volume to be smaller than your main memory minus some capacity for the server to run in. In my use case on a server with 32 GB RAM, I use a 30GB storage volume, and I see practically no disk access because the cached pages always fit in memory.<br>
