session - Subdomain cookie sharing in Rails 3 is not working (on Heroku)? -

-

i'm trying have cookies on site dapshare.com work both root address , 'www' subdomain.

a lot of other stackoverflow answers (and great railscasts vid on topic) have suggested adding line session_store.rb:

dapshare::application.config.session_store :cookie_store, :key => '_dapshare_session', :domain => :all

this doesn't seem make difference: if log in @ dapshare.com, still not logged in @ www.dapshare.com.

am doing wrong here? using following code store information in cookie:

cookies.permanent.signed[:thing_to_store] = store_information

thanks help!

short answer: using 'cookies[:new_cookie] =' not seem grab domain session_store config settings.

i added :domain new cookie , works:

cookies.permanent.signed[:new_cookie] = {:value => new_value, :domain => ".dapshare.com"}

for else reading, need specify domain when deleting cookie

cookies.delete :new_cookie, :domain => ".dapshare.com"

(thanks diagnosis andrew marshall.)

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

-
what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
