why is this coming
Is this something to do with proxy settings or ??
If so please let me know how to overcome this

hi,

HOW WE'RE DELETING COOKIES: : By java you can directly do this.

protected void deleteCookie(String cookieName)
{
String cookieDomain =
CTPropertiesManager.getProperty("site.properties",

"site.cookie.domain");

try
{
//get all cookies
Cookie cookies[] = request.getCookies();

Cookie ctCookie=null;
if (cookies !=null)
{
for(int i=0; i<cookies.length; i++)
{
ctCookie=cookies[i];
if (ctCookie.getName().trim().equals(cookieName))
{
if ( cookieDomain != null )
{
ctCookie.setDomain(cookieDomain);
}

ctCookie.setPath("/ct");
ctCookie.setMaxAge(0);
response.addCookie(ctCookie);
}
}//end for
}//end if cookie
}//end try
catch(Exception e){
CTLogManager.log(e);
}
}//end deleteCookie()



For deleting cache
You can create one bat file which clear your browser or application cache before test start. after creating bat file just call in your code before test start.

Hope this will help you little bit. Best of luck.

Best of luck

Thanks very much for your quick reply !!

Do we know how to do this kind of batch file in linux?

While this will work if you need to delete cookies/cache mid-test, if all you want to do is start a test with cookies and cache cleared, you can etiher rely on Selenium to start with a clean profile (fairly certain that is the default behavior) or use a custom generated completely clean user profile as an argument when launching SeleniumRC. I know that works for FF in the least.

Here's how to delete the browser cache without having restart the browser, or creating a brand new profile:
(1) Delete cookies, refresh browser
(2) Delete browser cache via javascript

public void clearBrowserCache() {
webDriver.manage().deleteAllCookies();
selenium.refresh();
webDriver.navigate().to("file:///c:/tmp/ClearCacheFirefox.html");
}

Contents of ClearCacheFirefox.html




Response.Cache.SetExpires(DateTime.Parse(DateTime.Now.ToString()))
Response.Cache.SetCacheability(HttpCacheability.Private)
Response.Cache.SetNoStore()
Response.AppendHeader("Pragma", "no-cache")

Oh yeah, you can call the javascript directly without putting in an html doc:

String jScript_ = "" +
"Response.Cache.SetExpires(DateTime.Parse(DateTime.Now.ToString()))\n" +
"Response.Cache.SetCacheability(HttpCacheability.Private)\n" +
"Response.Cache.SetNoStore()\n" +
"Response.AppendHeader("Pragma", "no-cache")";

selenium.getEval(jScript_);
