Adsense earnings drop when you use caching programs. I've had it go from earning $300 a day to $3.00 a day and when I turned off caching it went right back up to $300. This guy above is mistaken for saying it cached on google's side not yours. Your caching plugins will cache the google code, and it will not count your views just your clicks.
There's a proxy_cache_purge direction where you can use an access point to purge cache. Then you can use curl inside your cron job and execute that at a certain time.
No, it doesn't eat swap. It serves only as a block cache. It most cache, cache can't go out into swap, but some exceptions are existing for this rule, too. For example, caching a slow hard disk on a fast SSD could be a good thing. But, in your case, the situation is much more simple: Linux (and any other OS) uses all (or nearly all) of the free ram to ...
Using htop you can see some detailed information about processes interactively. For example: use F6 and select MEM% to sort by memory usage.
Adsense resources are hosted on google's side, not yours.
Configuring Cache-control only works with HTTP/1.1, to disable caching for older IE browsers, you need to configure Cache-control: no-cache Pragma: no-cache The following article provides more details on this: Disable Caching in ARR
Best guess is the browser will download it twice, and any optimization avoiding the second download would be very browser specific. However, this should be an easy enough thing to test, and I've just now done that :) With Firefox browser and JW Player, the video is loaded twice concurrently. Neither the browser nor flash is smart enough to optimize this ...
As you mentioned. while Varnish does not handle SSL it is possible to use a SSL termination proxy which passes to Varnish. The SSL termination proxy can add or remove headers and change ports so you should be able to create a flow that avoids redirect loops. Popular SSL termination proxies are Pound, Stunel, Nginx and HAProxy. The range of features you ...
What does cat /etc/default/cachefilesd say? Is it set to on? # Defaults for cachefilesd initscript # sourced by /etc/init.d/cachefilesd # You must uncomment the run=yes line below for cachefilesd to start. # Before doing so, please read /usr/share/doc/cachefilesd/howto.txt.gz as # extended user attributes need to be enabled on the cache filesystem. ...
Yes you can do it with Nginx. Use FastCGI cache for it. Here is one of many tutorials how to do it: https://www.digitalocean.com/community/tutorials/how-to-setup-fastcgi-caching-with-nginx-on-your-vps
If you have a UPS you can force the cache on and not use the batter on the raid. If you lose power without a raid card you can get corrupted data, thats what backups are for. And just because you lost power does not mean your system is toast. The cache only holds 256 megs and it gets flushed/written to HD all the time when idle. Its not like it holds ...
Dig reports the time left until the TTL expires rather than the actual TTL value. If the number varies, it is most likely that you're querying different DNS servers (for example, round robin) which have the record cached for different amounts of time, and therefore have different expiry times. If you run the same query against the same DNS server, you will ...
Moving the storage location of MySQLs data folder solved the issue. Be sure to correct security permissions on the new folder before restarting MySQL.
I had not heard of HyperDuo before now, and after reading their documentation, I now know why - it's a technology solely aimed at the consumer market. Additionally, their list of supported OSes does not include any Windows Server versions. So - I'd recommend returning this SATA controller and purchasing something that is purpose-built for server workloads - ...
You have completely wrong approach. Please do read more about Nginx proxy caching http://nginx.org/en/docs/http/ngx_http_proxy_module.html This can also be usefull: How to set up Nginx as a caching reverse proxy?
Your backend responds with < Cache-Control: max-age=2592000, public, must-revalidate, proxy-revalidate < Expires: Sat, 14 Feb 2015 19:33:58 GMT So does the original answer, and this overrides the proxy_cache_valid setting: Parameters of caching can also be set directly in the response header. This has higher priority than setting of caching time ...
I can think of one plausible reason to do this in a nightly cron job. On a large system, it may be useful to periodically drop caches so you can remove memory fragmentation. The kernel transparent hugepage support does a periodic sweep of memory to coalesce small pages into hugepages. Under degenerate conditions this can result in system pauses of a ...
I got the same behaviour with Squid 3.3.8 (package up to date on Ubuntu 14.10 at the time of writing) After digging here, I found out that the cache mishandling of CSS and JS when the Vary Header is present was effectively a bug, fixed in posterious releases. Installing Squid 3.4.10 from the sources, makes disapear this issue.
