c# - Getting "Stream not readable" when reading HttpWebResponse -

i'm trying "screen scrape" data have request follows (from fiddler)

post http://fallenlondon.storynexus.com/auth/emaillogin http/1.1 content-type: application/x-www-form-urlencoded referer: http://fallenlondon.storynexus.com/signup user-agent: mine accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8 cache-control: max-age=0 l:  origin: http://fallenlondon.storynexus.com/ dnt: 1 accept-encoding: utf-8 accept-language: en-gb,en;q=0.8 cookie: asp.net_sessionid=05xq3gndu4nczvy5wsah5qyw; __utma=100212060.1740063036.1431282067.1431282067.1431284767.2; __utmb=100212060.14.10.1431284767; __utmc=100212060; __utmz=100212060.1431282067.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none) host: fallenlondon.storynexus.com content-length: 54 

(the content credentials) - header matches request traced manually viewing web page in browser.

i send using httpwebrequest.getresponse() response back

http/1.1 200 ok access-control-allow-origin: * cache-control: no-cache, no-store, must-revalidate content-type: text/html; charset=utf-8 date: mon, 11 may 2015 20:54:15 gmt expires: -1 pragma: no-cache server: microsoft-iis/8.0 x-aspnet-version: 4.0.30319 x-aspnetmvc-version: 4.0 x-powered-by: asp.net x-server: web1 content-length: 16900 connection: keep-alive 

this (again) matches using browser. using fiddler, can see 17k of data (html), try read using...

var stream = response.getresponsestream(); if (stream == null) return null; using (var reader = new streamreader(stream, encoding.utf8)) {    var data = reader.readtoend();    reader.close();    return data; } 

i exception on "new streamreader" line stating "stream not readable" debugger shows me stream neither readable or writeable. 2nd page have read (the first 1 being simple request main url login page). works fine using same code. streams , requests have been closed after use.

google gives me no help, suggesting page error (no, status 200) or having read data (no, code goes straight here) not using threading @ that's not issue. have tried changing encoding (requesting gzip gives me smaller payload expected still can't read it) using c#.net 4.5.2 on win7 x64

does have idea i'm doing wrong?

d'oh! due "oversight" in code, trying read stream twice! working now
