When enabled Varnish will compress uncompressed objects before they are stored in the cache. If a client does not support gzip encoding Varnish will uncompress compressed objects on demand. Varnish will also rewrite the Accept-Encoding header of clients indicating support for gzip to:: - - Accept-Encoding: gzip - - Clients that do not support gzip will have their Accept-Encoding header removed. For more information on how gzip is implemented please see the chapter on gzip in the Varnish reference. - -http_max_hdr - - Units: header lines - - Default: 64 - - Maximum number of HTTP headers we will deal with in client request or backend reponses.

This is a limit on all bytes up to the double blank line which ends the HTTP request. - The memory for the request is allocated from the session workspace (param: sess_workspace) and this parameter limits how much of that the request is allowed to take up. - -http_resp_hdr_len - - Units: bytes - - Default: 4096 - - Maximum length of any HTTP backend response header we will allow. The limit is inclusive its continuation lines. - -http_resp_size - - Units: bytes - - Default: 32768 - - Maximum number of bytes of HTTP backend resonse we will deal with. This is a limit on all bytes up to the double blank line which ends the HTTP request. - The memory for the request is allocated from the worker workspace (param: sess_workspace) and this parameter limits how much of that the request is allowed to take up. - -listen_address - - Default: :80 - - Flags: must_restart - - Whitespace separated list of network endpoints where Varnish will accept requests. - Possible formats: host, host:port, :port - -listen_depth - - Units: connections - - Default: 1024 - - Flags: must_restart - - Listen queue depth. - -log_hashstring - - Units: bool - - Default: on - - Log the hash string components to shared memory log. - -log_local_address - - Units: bool - - Default: off - - Log the local address on the TCP connection in the SessionOpen shared memory record. - -lru_interval - - Units: seconds - - Default: 2 - - Flags: experimental - - Grace period before object moves on LRU list. - Objects are only moved to the front of the LRU list if they have not been moved there already inside this timeout period. This reduces the amount of lock operations necessary for LRU list access. - -max_esi_depth - - Units: levels - - Default: 5 - - Maximum depth of esi:include processing. - -max_restarts - - Units: restarts - - Default: 4 - - Upper limit on how many times a request can restart. - Be aware that restarts are likely to cause a hit against the backend, so don't increase thoughtlessly. - -nuke_limit - - Units: allocations - - Default: 10 - - Flags: experimental - - Maximum number of objects we attempt to nuke in orderto make space for a object body. - -ping_interval - - Units: seconds - - Default: 3 - - Flags: must_restart - - Interval between pings from parent to child. - Zero will disable pinging entirely, which makes it possible to attach a debugger to the child. - -pipe_timeout - - Units: seconds - - Default: 60 - - Idle timeout for PIPE sessions. If nothing have been received in either direction for this many seconds, the session is closed. - -prefer_ipv6 - - Units: bool - - Default: off - - Prefer IPv6 address when connecting to backends which have both IPv4 and IPv6 addresses. - -queue_max - - Units: % - - Default: 100 - - Flags: experimental - - Percentage permitted queue length. - - This sets the ratio of queued requests to worker threads, above which sessions will be dropped instead of queued. - -rush_exponent - - Units: requests per request - - Default: 3 - - Flags: experimental - - How many parked request we start for each completed request on the object. - NB: Even with the implict delay of delivery, this parameter controls an exponential increase in number of worker threads. - -saintmode_threshold - - Units: objects - - Default: 10 - - Flags: experimental - - The maximum number of objects held off by saint mode before no further will be made to the backend until one times out. A value of 0 disables saintmode. - -send_timeout - - Units: seconds - - Default: 60 - - Flags: delayed - - Send timeout for client connections. If the HTTP response hasn't been transmitted in this many - seconds the session is closed. - See setsockopt(2) under SO_SNDTIMEO for more information. - -sess_timeout - - Units: seconds - - Default: 5 - - Idle timeout for persistent sessions. If a HTTP request has not been received in this many seconds, the session is closed. - -sess_workspace - - Units: bytes - - Default: 65536 - - Flags: delayed - - Bytes of HTTP protocol workspace allocated for sessions. This space must be big enough for the entire HTTP protocol header and any edits done to it in the VCL code. - Minimum is 1024 bytes. - -session_linger - - Units: ms - - Default: 50 - - Flags: experimental - - How long time the workerthread lingers on the session to see if a new request appears right away. - If sessions are reused, as much as half of all reuses happen within the first 100 msec of the previous request completing. - Setting this too high results in worker threads not doing anything for their keep, setting it too low just means that more sessions take a detour around the waiter. - -session_max - - Units: sessions - - Default: 100000 - - Maximum number of sessions we will allocate before just dropping connections. - This is mostly an anti-DoS measure, and setting it plenty high should not hurt, as long as you have the memory for it. - -shm_reclen - - Units: bytes - - Default: 255 - - Maximum number of bytes in SHM log record. - Maximum is 65535 bytes. - -shm_workspace - - Units: bytes - - Default: 8192 - - Flags: delayed - - Bytes of shmlog workspace allocated for worker threads. If too big, it wastes some ram, if too small it causes needless flushes of the SHM workspace. - These flushes show up in stats as "SHM flushes due to overflow". - Minimum is 4096 bytes. - -shortlived - - Units: s - - Default: 10.0 - - Objects created with TTL shorter than this are always put in transient storage. - -syslog_cli_traffic - - Units: bool - - Default: on - - Log all CLI traffic to syslog(LOG_INFO). - -thread_pool_add_delay - - Units: milliseconds - - Default: 2 - - Wait at least this long between creating threads. - - Setting this too long results in insuffient worker threads. - - Setting this too short increases the risk of worker thread pile-up. - -thread_pool_add_threshold - - Units: requests - - Default: 2 - - Flags: experimental - - Overflow threshold for worker thread creation. - - Setting this too low, will result in excess worker threads, which is generally a bad idea. - - Setting it too high results in insuffient worker threads. - -thread_pool_fail_delay - - Units: milliseconds - - Default: 200 - - Flags: experimental - - Wait at least this long after a failed thread creation before trying to create another thread. - - Failure to create a worker thread is often a sign that the end is near, because the process is running out of RAM resources for thread stacks. - This delay tries to not rush it on needlessly. - - If thread creation failures are a problem, check that thread_pool_max is not too high. - - It may also help to increase thread_pool_timeout and thread_pool_min, to reduce the rate at which treads are destroyed and later recreated. - -thread_pool_max - - Units: threads - - Default: 500 - - Flags: delayed, experimental - - The maximum number of worker threads in each pool. - - Do not set this higher than you have to, since excess worker threads soak up RAM and CPU and generally just get in the way of getting work done. - -thread_pool_min - - Units: threads - - Default: 5 - - Flags: delayed, experimental - - The minimum number of worker threads in each pool. - - Increasing this may help ramp up faster from low load situations where threads have expired. - - Minimum is 2 threads. - -thread_pool_purge_delay - - Units: milliseconds - - Default: 1000 - - Flags: delayed, experimental - - Wait this long between purging threads. - - This controls the decay of thread pools when idle(-ish). - - Minimum is 100 milliseconds. - -thread_pool_stack - - Units: bytes - - Default: -1 - - Flags: experimental - - Worker thread stack size. - On 32bit systems you may need to tweak this down to fit many threads into the limited address space. - -thread_pool_timeout - - Units: seconds - - Default: 300 - - Flags: delayed, experimental - - Thread idle threshold. - - Threads in excess of thread_pool_min, which have been idle for at least this long are candidates for purging. - - Minimum is 1 second. - -thread_pool_workspace - - Units: bytes - - Default: 65536 - - Flags: delayed - - Bytes of HTTP protocol workspace allocated for worker threads. This space must be big enough for the backend request and responses, and response to the client plus any other memory needs in the VCL code.Minimum is 1024 bytes. - -thread_pools - - Units: pools - - Default: 2 - - Flags: delayed, experimental - - Number of worker thread pools. - - Increasing number of worker pools decreases lock contention. - - Too many pools waste CPU and RAM resources, and more than one pool for each CPU is probably detrimal to performance. - - Can be increased on the fly, but decreases require a restart to take effect. - -thread_stats_rate - - Units: requests - - Default: 10 - - Flags: experimental - - Worker threads accumulate statistics, and dump these into the global stats counters if the lock is free when they finish a request. - This parameters defines the maximum number of requests a worker thread may handle, before it is forced to dump its accumulated stats into the global counters. - -user - - Default: magic - - Flags: must_restart - - The unprivileged user to run as. Setting this will also set "group" to the specified user's primary group. - -vcc_err_unref - - Units: bool - - Default: on - - Unreferenced VCL objects result in error. - -vcl_dir - - Default: /usr/local/etc/varnish - - Directory from which relative VCL filenames (vcl.load and include) are opened. - -vcl_trace - - Units: bool - - Default: off - - Trace VCL execution in the shmlog. - Enabling this will allow you to see the path each request has taken through the VCL program. - This generates a lot of logrecords so it is off by default. - -vmod_dir - - Default: /usr/local/lib/varnish/vmods - - Directory where VCL modules are to be found. - -waiter - - Default: default - - Flags: must_restart, experimental - - Select the waiter kernel interface. - - | ||
