Issue "prerender" 'on the fly'? -


is possible issue prerender statement 'on fly'? e.g. use jquery insert in

<link rel="prerender" href="www.example.com" />

into , execute? there way re-issue x times?

basically, when adds shopping cart want prerender checkout page, can't @ page load because prerender checkout page without new item added.

thanks

yes, possible use js adding prerender hint , can update url page should prerendered. basically, browser "forget" prerendered page , prerender new one. but, have careful, if browser doesn't have enough time prerender checkout page, user see stale checkout page.

considering case, need use query parameter, otherwise, browser won't prerender checkout page again after updating href attribute, because in cache. example, urls might like:

/checkout?timestamp=111111 /checkout?timestamp=222222 /checkout?timestamp=333333

the user must visit page latest query parameter (/checkout?timestamp=333333), otherwise, browser load checkout page.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
