USAGE;TS;;i@o; ;[ I"General CGI scripts ;TI"^^^^^^^^^^^^^^^^^^^ ;TI"SThe most efficient way to use LSAPI interface is to modify your CGI scripts. ;TI"<You need to add the following code to your CGI scripts:;T@o;;[
I"require 'lsapi'
;TI"
;TI" while LSAPI.accept != nil
;TI"
;TI" <your CGI script>
;TI" ...
;TI"
;TI" end
;T;0o; ;[I"LThere is no need to change the way that how CGI environment variables ;TI"(are being accessed in your scripts.;T@o; ;[I"7You can find some examples under examples/ folder.;T@o; ;[ I"Ruby Script Runner ;TI"^^^^^^^^^^^^^^^^^^ ;TI"OIf you don't want to change your existing Ruby CGI code, you can use our ;TI"FRuby script runner under scripts/ folder. You need to configure ;TI"Ilsruby_runner.rb as a LSAPI application, then add a script handler ;TI"for "rb" suffix.;T@@o; ;[I"Rails dispatcher ;TI"^^^^^^^^^^^^^^^^;T@o; ;[I"RWith Ruby LSAPI, we proudly provide a optimum platform for Rails application ;TI"Ndeployment. Ruby LSAPI has the following advantages over other solutions.;T@o;;[ I"M* Easy configuration, deploy a Rails application only take a few clicks
;TI") with our Rails easy configuration
;TI"M* Fast startup, the expensive Rails framework initialization only takes
;TI"= place once when multiple processes need to be started
;TI"J* Resource efficience, ruby processes can be started on demand, idle
;TI" process will be stop.
;T;0o; ;[I"DTo use LSAPI with Ruby on Rails, please check out our toturial ;TI"7http://www.litespeedtech.com/support/wiki/doku.php;T@o; ;[I"MThere are a few environment variables that can be tweaked to tune ruby ;TI"LSAPI process.;T@o:RDoc::Markup::List:
@type: BULLET: @items[o:RDoc::Markup::ListItem: @label0;[o; ;[I"/LSAPI_CHILDREN (default: 0);T@o; ;[ I"MLSAPI_CHILDREN controls the maximum number of children processes can be ;TI"Ostarted by the first ruby process started by web server. When set to <=1, ;TI"Pthe first ruby process will handle request by itself, without starting any ;TI"Rchild process. When LSAPI_CHILDREN is >1, the LSAPI application is stared in ;TI"O"Self Managed Mode", which will start children processes based on demand. ;TI"JWith Rails easy configuration, LSAPI_CHILDREN is set to the value of ;TI"C"Max Connections" by web server, no need to set it explicitly.;T@o; ;[I"OUsually, there is no need to set value of LSAPI_CHILDREN over 100 in most ;TI"server environment.;T@o;;;;[o;;0;[o; ;[I"/LSAPI_AVOID_FORK (default: 0);T@o; ;[ I"NLSAPI_AVOID_FORK specifies the policy of the internal process manager in ;TI"P"Self Managed Mode". When set to 0, the internal process manager will stop ;TI"Kand start children process on demand to save system resource. This is ;TI"Lpreferred in a shared hosting environment. When set to 1, the internal ;TI"Pprocess manager will try to avoid freqently stopping and starting children ;TI"Hprocess. This might be preferred in a dedicate hosting environment.;T@o;;;;[o;;0;[o; ;[I"HLSAPI_EXTRA_CHILDREN (default: 1/3 of LSAPI_CHILDREN or 0);T@o; ;[ I"RLSAPI_EXTRA_CHILDREN controls the maximum number of extra children processes ;TI"Hcan be started when some or all existing children processes are in ;TI"Qmalfunctioning state. Total number of children processes will be reduced to ;TI"@LSAPI_CHILDREN level as soon as service is back to normal. ;TI"DWhen LSAPI_AVOID_FORK is set to 0, the default value is 1/3 of ;TI"OLSAPI_CHIDLREN, When LSAPI_AVOID_FORK is set to 1, the default value is 0.;T@o;;;;[o;;0;[o; ;[I"9LSAPI_MAX_REQS (default value: 10000);T@o; ;[I"HLSAPI_MAX_REQS specifies the maximum number of requests each child ;TI"Kprocess will handle before it exits automatically.

;T;0o; ;[ I"JIn Self Managed Mode, LSAI_MAX_IDLE_CHILDREN controls how many idle ;TI"Gchildren processes are allowed.
