For preserving the search criteria on some page of our web application we're saving the different settings of the
search filters into a cookie. So, when the user comes back next time we can restore the search filter settings that
have been used previously.
Now however one of my working colleagues had the problem that some strings where
not correctly retrieved from the cookie. Actually it was a character encoding problem. Characters like "ü,ö,.." were
not displayed correctly after retrieving them from the cookie. I'm not sure whether you can set the character encoding
of cookies. I don't think so, I've however not done any deep search on the web. Our solution was to do an
url-encoding/decoding on the "critical" values of the cookie. So you can do something like
public void SaveValuesToCookie(){
...
Response.Cookies["key1"]["valuekey"] = Server.UrlEncode(criticalValue);
...
}
public void LoadValuesFromCookie(){
...
retrievedValue = Server.UrlDecode(Request.Cookies["key1"]["valuekey"]);
...
}
