mod rewrite - Refactoring a mod_rewrite depending if query string exisits -

- 

rewritecond %{query_string} lang_opt\=e   rewriterule /lc/courses.asp english-resource [r=301,nc,l]  rewritecond %{query_string} lang_opt\=f   rewriterule /lc/courses.asp french-resource  [r=301,nc,l]  rewriterule /lc/courses.asp english-resource [r=301,nc,l]

a link comes in 3 flavors
/lc/courses.asp
/lc/courses.asp?lang=e
/lc/courses.asp?lang=f

is there more elegant way deal these 3 variations of link. have quite few of them , 5 line of mod_rewite per seems excessive.

thanks

since english default, need french , redirect else english:

rewritecond %{query_string} lang_opt=f rewriterule ^/lc/courses\.asp$ french-resource  [r=301,nc,l] rewriterule ^/lc/courses\.asp$ english-resource [r=301,nc,l]

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.
