i trying login credentials .net site unable working. code inspired below thread

how login , download file aspx web pages r

library(rcurl) curl = getcurlhandle() curlsetopt(cookiejar = 'cookies.txt', followlocation = true, autoreferer = true, curl = curl) html <- geturl('http://www.aceanalyser.com/login.aspx', curl = curl) viewstate <- as.character(sub('.*id="__viewstate" value="([0-9a-za-z+/=]*).*', '\\1', html)) viewstategenerator <- as.character(sub('.*id="__viewstategenerator" value="([0-9a-za-z+/=]*).*', '\\1', html))  params <- list(   'txtuserid'    = '********',   'txtpwd'    = '*******',   'btn_login' = 'go',   '__viewstate' = viewstate,   '__viewstategenerator' = viewstategenerator,   'hiddenfield1' = '1280',   'hiddenfield2' = '700',   'hdn_pwd' = 'true')  html = postform('http://www.aceanalyser.com/login.aspx', .params = params, curl = curl) grepl('logout', html)

result: false

please me understand issue

you may change option 'btn_login' = 'go' like

'btn_login.x' = '22', 'btn_login.y' = '14'

according this, reason bug.

some browsers (iirc versions of internet explorer) send co-ordinates of image map (in name.x , name.y) , ignore value.
