http://groups.google.com/group/mod_cache Mod-Cache is a cache(reverse-proxy) plugin for lighttpd, which works like Squid with similar configuration. However mod_cache is faster and more effective than Squid because it based on powerful Lighttpd. 2009-11-05T05:25:51Z Google Groups yaoxing zhang yaoxing.zh...@gmail.com 2009-11-05T05:25:51Z http://groups.google.com/group/mod_cache/browse_thread/thread/cadccfe33b535878/c3c645af98929616?show_docid=c3c645af98929616

alright, find the solution. simply move mod_mem_cache after mod_expire <br> would resolve the problem. <br> thank you for your patient help. <br> Regards, <br> YX

Hi again, <br> I tried mod_mem_cache, it works fine. But I also noticed that expires <br> header is removed. I'm not sure yet whether it's because of lighttpd <br> upgrading or mod_mem_cache patch. is there any known issue of mod_mem_cache? <br> Regards, <br> YX

when one file is cached in application, then there has no disk read access <br> to it for long time, so OS will remove it from cache soon for caching other <br> files.

Should application cache open files with NO CACHE flags to inform OS <br> not to cache it? <br> Or else, there would be two copies in memory, one is app's ,the other is OS's. <br> 2009/11/5 shellcode &lt;shellc...@gmail.com&gt;:

OS try to cache every files recently accessed into memory, then OS will drop <br> some cached files at any time. <br> mod_mem_cache/mod_cache caches files that are useful for web service only. <br> In summary, sometimes OS cache isn't good enough for faster web service and <br> application cache works good enough

mod_cache now natively support cache files into memory, do not need <br> load mod_mem_cache any more. <br> <p>Kevin Yu <br> Mail: flyin...@gmail.com

I think operating system should cache frequently accessed files into <br> memory, lighty does not need to control it. Am I right? <br> 2009/11/4 shellcode &lt;shellc...@gmail.com&gt;:

mod_cache is to cache remote files to local disk/memory, so mod_proxy is <br> needed for mod_cache. <br> mod_mem_cache is to cache local files into memory

Thank you. Does it mean, mod_cache must work with a back end proxy? <br> Regards, <br> YX

for local static file caching, you need mod_mem_cache, not mod_cache <br> mod_mem_cache doc is <br> <a target="_blank" rel=nofollow href="http://redmine.lighttpd.net/projects/lighttpd/wiki/Docs:ModMemCache">[link]</a>

no mod_proxy. it's a image server that only serves static images. <br> And here is the curl result: <br> &gt; GET /ProductImages/sku_0005_1.jpg HTTP/1.1 <br> &gt; User-Agent: curl/7.15.5 (x86_64-redhat-linux-gnu) libcurl/7.15.5 <br> OpenSSL/0.9.8b zlib/1.2.3 libidn/0.6.5 <br> &gt; Host: 75.126.135.148 <br> &gt; Accept: */* <br> &gt; <br> &lt; HTTP/1.1 200 OK

Is it possible that some modules maybe conflicting with mod_cache? <br> I have the following modules enabled: <br> mod_cache <br> mod_rewrite <br> mod_access <br> mod_expire <br> mod_accesslog <br> and configured with <br> --with-fam <br> --with-ssl <br> Regards, <br> YX
