node.js - Using multiple proxies via request.js -

-

i trying send list of proxy addresses requestjs & want use first 1 that's working. @ possible via request.js

my code 

 var body = '<sample/>';  request.post({                 url: www.google.com,                 proxy':'http://proxy1:8087;http://proxy2:8080',//need use multiple proxies here.                 headers: { //we can define headers                     'content-type': 'text/xml'                 },                 body: body,                 timeout:20000             }

i thinking of looping through list of proxies , try use them 1 one. not sure if have been overkill or way possible.

requestjs cannot loop through proxies, best possible option use agent module alongwith https://www.npmjs.com/package/pac-proxy-agent

but module not iterate through list now. feasible option loop through list of proxies , use first 1 reachable now.

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
