PHP Sessions on Auto-Scaling Servers -

-

i'm working on php web app deployed amazon web services. have load balancers in front of auto-scaled application servers.

the problem we're facing @ moment handling sessions. while sticky sessions reasonable solution, we'd persist sessions quite long time (weeks ideally). impair performance of load balancer on time. also, using auto-scaling mean that, time time, we'll remove server , lose of active sessions on it. of course, use common database store sessions, i'm bit concerned performance if every request requires round-trip db.

i'd grateful if suggest solutions have worked you, or ideas try.

thanks in advance help, ross

i use custom session solution sessions stored in datatabase.

that way webservers have access same session store , can decide self how long session should kept.

you either build works php normal sessions or stand alone class handle them.

i did similar share session between asp , asp.net on different serves , works.

if performance issue, use separate database, memcached or mysql cluster (also memory stored) or maybe mongodb sessions.

magically formatted comments change reported line number of javascript errors in browsers; this: //@line n "f" n line number , f file name. unfortunately, //@line appears ungoogleable. know there documentation on feature, , browsers support it?

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
