.net - VB.NET - [HTTP POST] Response.Cookies is only returning first cookie value -

i'm using following code loop throught response cookies , save them in cookiejar.

    each tempcookie cookie in response.cookies         cookiejar.add(tempcookie)         msgbox(tempcookie.tostring)     next 

it happens it's returning 1 cookie, first 1 (only runs once in for):

 page_vis=a|186.213.98.144|1381089446.485193| 

response.cookies has 1 cookie on it, response.headers has of them.

how parse them response.headers , add on cookiecontainer use them later? cookies in response.headers here:

why isn't getting rest of cookies, first one?
how solve that?

the entire function in here:

private function logonpage(byval url string, byref cookiejar cookiecontainer, byval postdata string)     dim reader streamreader      dim request httpwebrequest = httpwebrequest.create(url)      request.method = "post"     request.useragent = "mozilla/5.0 (windows; u; windows nt 5.1; en-us; rv:1.8.1.14) gecko/20080404 firefox/2.0.0.14"     request.cookiecontainer = cookiejar     request.allowautoredirect = false     request.contenttype = "application/x-www-form-urlencoded"     request.contentlength = postdata.length      dim requeststream stream = request.getrequeststream()     dim postbytes byte() = encoding.ascii.getbytes(postdata)      requeststream.write(postbytes, 0, postbytes.length)     requeststream.close()      dim response httpwebresponse = request.getresponse()      each tempcookie cookie in response.cookies         cookiejar.add(tempcookie)     next      reader = new streamreader(response.getresponsestream())     return reader.readtoend()     response.close() end function 

tell me i'm doing wrong, , if it's possible, point me solution? thank much.

in case of multiple cookies, set-cookie header might contain cookies separated comma , while cookie properties separated semicolon ; , response.headers("set-cookie") returns cookies in string.

1. apply cookie separation technique on response.headers("set-cookie")
2. extract each cookie's name, value, path, domain etc.
3. create cookie objects information
4. add cookies cookiecontainer.

note splitting cookies on comma , not useful because cookie property expires might contain comma in expires=mon, 07-oct-2013 06:00:00 gmt:

dim strcookies string = response.headers("set-cookie")  ' splitting on comma example dim cookies() string = strcookies.split(commadelimeter, stringsplitoptions.removeemptyentries)  each ck string in cookies     dim ckprop() string = ck.split(semicolondelimeter, stringsplitoptions.removeemptyentries)     dim cookie new cookie(ckprop(0), ckprop(1))     cookiejar.add(cookie)         next ck
