For populating the cache, have you looked at the error_file directive.
You can set the error file to script which could be passed to an FCGI
process, so that on a cache-miss the script is called to generate the
page, which could in the process put the file into the memcached
cache. </div></blockquote><div><br>Marcus, <br><br>I believe Daniel was talking about the opposite. He want to populate the cache if nginx hits the file instead of when it does not find it.<br><br>So something like this (this is how nginx would do it<br>

<br>What Daniel wants (if I understood correctly)<br>request comes from /files/1.txt<br>
1. Check if memcache exists and serve from there.<br>
2. if(-f file ) call the perl/fcgi process that populates the memcache cache and returns the file. (so this would be done only where there is no cache in memcache)<br>3. If file does not exists, handle error.<br>
<br><br>Still I dont see whats the point of this but yes it is doable.<br><br>best regards<br><br><br><br><br> <br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

I see now your other posts, <br>
<br>
I do not think that you will get any benifit of using memcached with
static files.<br>
Nginx is already very optimized at serving static files.<br>

is purely speculative, so please don't think I know how to do this.
I'm throwing this out so hopefully, if a good idea, the right people
can create the example.<br>
<br>
Memcached has a good assortment of Perl clients.<br>
<br>
Nginx has a means of embedding Perl into the configuration.<br>
<br>
Couldn't there be a way of combining these to immediately populate the
cache when the cache returns missing?<br>
<br>
By the way, I'm looking at this as a means of improving I/O for static
pages (on SliceHost). Ideally nginx's Memcached Module would have the
ability to do this when the requested filename exists on the hard drive:<br>
(-f $request_filename/index.html)<br>
