You were pointed into the right direction with KB946358. LSA cache is being purged when server restarts or may be disabled entirely (but this will require restart first). I'm very interested in finding precise reproduction steps for this. See my question about this - still no answer so far, but it contains a solution which doesn't require reboot to fix your ...

Nginx is good enough for cache responses from S3, it also supports cache invalidation on demand, for example: curl -I 'https://domain/s3/file.jpg' -H 'Cache-Purge: 1' In case of caching proxy Nginx doesn't do subsequent HTTP request to S3 if the response is on disk already (file name based on proxy directory + md5 of response). See the full config there: ...

Just put the files here. /etc/nginx/sites-available/site1/ And do soft link ln -s /etc/nginx/sites-available/site1/ /etc/nginx/sites-enabled/site1/

Put include /etc/nginx/conf.d/*.conf; after the cache declaration, not before.

Nginx packaging changed : the conf.d folder was used in old packages, sites-enabled / sites-available is used now with sites-available directory containing actual vhosts configurations and sites-enabled the symlinks to sites-available vhosts you want to activate. So a typical structure would now be : nginx ├── nginx.conf ├── sites-available │   ├── mysite1 ...

dm-cache wasn't merged until 3.9 and bcache wasn't merged until 3.10. EnhanceIO is a fork of flashcache which some optimizations that also is available on 3.10. There have been a lot of advancements since 2.6.32 in the kernel and there aren't any backports for these features in the RHEL6 kernel which OpenVZ is based off of. OpenVZ will be releasing a beta ...

I agree with answers above, since Apple is using strong encryption, it's probably not easy to do what you said using 3rd party applications. BUT Apple has it's own solution for that, OS X Server, it has a function called Caching server: https://www.apple.com/osx/server/features/#caching-server Caching Server speeds up the download and delivery of ...

I was overcomplicating... (and a little ignorant of Apache conf expressions). This did it. <If "%{QUERY_STRING} =~ /v\d{8}$/"> Header set Cache-Control "max-age=31535999, public" </If>

This was not easy to find, but in inetpub\temp\appPools\ there was a folder named as the application pool. In that folder there is "copy" of parts of the IIS config. At some point we must have accidentally marked the actual asmx file, instead of the folder when we changed autentication. So it contained a special configuration section for just the file. ...

You need to add the caching directives to your default.conf file, and remove this new file you created. Your new file is only used when users visit the site using http://localhost. In addition, your new file configuration is using different paths compared to your default.conf file. Also, the root directive inside a location block is bad practice. So, your ...

thanks @myaut for the guidance, i looked up the _spin_lock_irqsave and it turned out to be related to the kernel itself and not Nginx. Acording to this article, the problem can be fixed by disabling RedHat Transparent Huge Page feature which fixed the problem. echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled
