java - CSV download does not work over SSL -


we seeing problem on our qa environment download csv feature not working expected. file downloaded, looks content-disposition header lost. 

response.setcontenttype("text/csv"); response.setheader("content-disposition", "attachment; filename=\""+pagename+".csv\""); response.getoutputstream().print(content); response.getoutputstream().flush(); response.getoutputstream().close();

this code runs fine on local workspace , dev environment on http. on qa, on https, file downloaded without .csv extension. chrome browser inspect shows content-disposition header missing. have tried switching qa environment http, , works expected.

initial research seemed point cache-control header being set no-cache. have fixed settings @ proxy server, cache-control header no longer set 'no-cache', problem persists. using spring jsps running on jboss eap 6.4.0 , in case helps know.

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...
