http-error

I saw a lot of articles and questions about error handling using retrofit combined with RxAndroid, but i am not able to set my configuration right. What do I want to accomplish: when receiving a 4xx code: handle it on onError() when receiving a 2xx code: -> try to parse to expected response and deliver it onNext() -> If not possible try to convert the JSON answer to MyAPIError class (simple POJO with errorNum and message) and deliver it on onError. So either 2xx or 4xx http codes might end up in onError(). What do I have at the moment: ServiceGenerator.java public class ServiceGenerator {

I am trying to crawl the user's ratings of cinema movies of imdb from the review page: (number of movies in my database is about 600,000). I used jsoup to parse pages as below: (sorry, I didn't write the whole code here since it is too long) try { //connecting to mysql db ResultSet res = st .executeQuery("SELECT id, title, production_year " + "FROM title " + "WHERE kind_id =1 " + "LIMIT 0 , 100000"); while (res.next()){ ....... ....... String baseUrl = "http://www.imdb.com/search/title?release_date=" + ""+year+","+year+"&title="+movieName+"" + "&title_type=feature,short,documentary,unknown";

Our console applications are making hundreds of WebRequests to Facebook every minute (with using multiple apps and hundreds of access tokens). Now, they started to fail with the exception message in the title ("The request was aborted: The request was canceled"). We searched for hours on the internet, and tried out every possible solution, but nothing helped. These didn't help: webRequest.Timeout = 20000; //A request that didn't get respond within 20 seconds is unacceptable, and we would rather just retry. webRequest.KeepAlive = false; webRequest.ProtocolVersion = HttpVersion.Version10;

According to Microsoft's documentation , for static (i.e. HTML) content, web.config should read responseMode="File" for each error. Currently, my web.config includes <httpErrors errorMode="Custom"> <!-- remove statusCodes --> <error statusCode="404" path="/error/404.html" responseMode="ExecuteURL" /> </httpErrors> This returns the correct custom error page, but returns a 200 OK status code. When I change "ExecuteURL" to "File", my server does return a 404, but the custom error page is not displayed. Instead, I get the message "The resource you are looking for has been removed, had its name
