Hi friends,i upload the files using fileupload control.I uplod file succesfully but when i view uploaded file whose name include ".." the server gives HTTP error 400 bad request.For example i want to upload "example+pa...jpg" .The file uploads sucessfully to uploads directory and insert its path into database but when i view this file from different page using select from database its path, the server gives bad request error.Another problem;If i want to upload "example+pa.jpg" ,the file name seems "example pa" in address bar then server gives the The resource can not be found.it is normal because file paths are not be same.What are your advices ?i think something.i can write regular expression if file name include "+" ,system gives erorr message using this regular expression.
