Open_file_cache_min_uses is the amount of times a file needs to be requested before it is added to the open_file_cache. If you also enable open_file_cache_errors then set this directive a little higher. The files also need to be requested this many times within the “inactive” time frame in the open_file_cache directive. The default is 1 for this directive which is fine for most uses. So if “inactive=1h;” like in the example above and open_file_cache_min_uses is 3 then any client needs to request the same file at least three(3) times in 1 hour for the open file pointer to be cached. No need to have our cache filled with errors which were only called once.
} Instead of using the “include mime. This is especially useful option if you want to use the same mime types on many different systems or do not want to rely on a secondary definition file. Types” directive you can define your own mime types. In our example we define the extension “bob” as a text/plain. You also have the option of defining a mime type for a non-standard extension.
Doing a ifconfig -m does not show WOL capabilities but that doesn't make sense since freebsd uses the official intel igb driver and it does .
Use a program like pngcrush to make your PNG files smaller. Make your pictures small and efficient: If you do not need a big JPG on your page then make it smaller. The majority of bandwidth used today is for pictures according to Yahoo and Google. It to compress your images for you and download the result. Take a look at Google’s Optimizing web graphics for more ideas on making your pictures smaller. Crop out any extra sections of the picture that are not needed or even blur the background to allow the compression algorithm the be more efficient. You can save a lot of bandwidth and increase response time by serving optimized pictures. If you prefer a web based tool, Yahoo offers Yahoo Smush.
When this time runs out the clients ssl session information is removed from the “ssl_session_cache”. Depending on the client browser, they may or may not respect your ssl_session_timeout value if it larger than 5 minutes. Ssl_session_timeout 5m; is the cache session timeout between the client and the server set at 5 minutes or 300 seconds. If you expect the client to stay on your site longer and go to multiple pages you can always increase this default value. The reason this number was chosen is it also the default amount of time many client browsers will cache an ssl session.
This will show you how the system will behave when it is being used normally. You do not want to run your server at 100% utilization in production so stress testing is not good way to find out what the server will look like in production. Stress testing is only good to find out what your system can do in the worst possible scenario (DDOS. For real world testing look at what your normal traffic load looks like at your busiest times of the day.
Gzip_static does not depend on the gzip filter nginx module so you can use gzip_static without compiling the gzip filter. Gzip_static on; allows one to have pre-compressed. To use this option simply have a compressed copy of the same. Gzip_static can also be set to always to send out the compressed file no matter if the client specifies compression of not. For example, if we have the index. Html file in document root. Gz files served instead of compressing files on the fly. You will have a non-compressed copy for older clients which do not accept compression and a pre-compressed copy for all other clients. This is the most efficient method of serving compressed data. Html file in place we will also have a pre-compressed index.
1 clients use the proper headers so they can always ask for compressed data. 0 allows the server to send compressed data to HTTP/1. Most new browsers use SPDY and compression headers are ignored on SPDY connections.
In the example we have also added the ability to cache data on the proxy so requests do not have to go all the way to the back end servers. You can also configure Nginx to compress http calls back to the client in real time, thus saving bandwidth. This is a good idea to limit bad clients from abusing your web servers. Commonly ask for data is quickly served from the proxy reducing the load of your infrastructure. We have also added client request rate limiting.
Let’s look at both. There are two option regarding Nginx log rotation: you can use logrotate or you can write your own script. If you are running on OpenBSD or FreeBSD using the simple script method might be better. Using logrotate is good if you are on a Linux system and it is available.

In our example we will allow the clients coming from localhost (127. With the handshake proxied, PF itself will complete the handshake with the client, initiate a handshake with the server, and then pass packets between the two. Use this function to allow internal LAN clients access to the status pages or employee contact information and deny other clients. BTW, if you use OpenBSD’s pf packet filter firewall we highly suggest enabling “synproxy” in your pf. PF has the ability, however, to proxy the handshake. 1/32) and internal LAN ips 10. Normally when a client initiates a TCP connection to a server, PF will pass the handshake packets between the two endpoints as they arrive. Access control list : This is a way you can define a directory and only allow clients coming from the specified ips to have access. The benefit of this process is that no packets are sent to the server before the client completes the handshake. Conf for all connections to your web server. This eliminates the threat of spoofed TCP SYN floods affecting the server because a spoofed client connection will be unable to complete the handshake. 0/24 to access the protected “secure” directory.
