How to Allow Cross Domain Ajax Requests


ENABLE CROSS-DOMAIN 
Browser does not allow cross domain AJAX requests due to security issues. Cross-domain requests are allowed only if the server specifies same origin security policy.

To enable CORS, You need to specify below HTTP headers in the server.
  • Access-Control-Allow-Origin – Name of the domain allowed for cross domain requests. * indicates all domains are allowed.
  • Access-Control-Allow-Methods – List of HTTP methods can be used during request.
  • Access-Control-Allow-Headers – List of HTTP headers can be used during request.
In PHP, you can use the below code to set the headers.

header('Access-Control-Allow-Origin: *'); //I have also tried the * wildcard and get the same response
header("Access-Control-Allow-Credentials: true");
header('Access-Control-Allow-Methods: GET, PUT, POST, DELETE, OPTIONS');
header('Access-Control-Max-Age: 1000');
header('Access-Control-Allow-Headers: Content-Type, Content-Range, Content-Disposition, Content-Description');
In JAVA, you can use the below code to set the headers.

header("Access-Control-Allow-Origin: *");

Java Loops II print each element of our series as a single line of space-separated values.

We use the integers  ,  , and   to create the following series: You are given   queries in the form of  ,  , and  . For each query, print the series corresponding to the given  ,  , and   values as a single line of   space-separated integers. Input Format The first line contains an integer,  , denoting the number of queries.  Each line   of the   subsequent lines contains three space-separated integers describing the respective  ,  , and   values for that query. Constraints Output Format For each query, print the corresponding series on a new line. Each series must be printed in order as a single line of   space-separated integers. Sample Input 2 0 2 10 5 3 5 Sample Output 2 6 14 30 62 126 254 510 1022 2046 8 14 26 50 98 Explanation We have two queries: We use  ,  , and   to produce some series  : ... and so on. Once we hit  , we print the first ten terms as a single line of space-separate

Java Substring Comparisons

We define the following terms: Lexicographical Order , also known as  alphabetic  or  dictionary  order, orders characters as follows:  For example,  ball < cat ,  dog < dorm ,  Happy < happy ,  Zoo < ball . A  substring  of a string is a contiguous block of characters in the string. For example, the substrings of  abc  are  a ,  b ,  c ,  ab ,  bc , and  abc . Given a string,  , and an integer,  , complete the function so that it finds the lexicographically  smallest  and  largest substrings of length  . Input Format The first line contains a string denoting  . The second line contains an integer denoting  . Constraints  consists of English alphabetic letters only (i.e.,  [a-zA-Z] ). Output Format Return the respective lexicographically smallest and largest substrings as a single newline-separated string. Sample Input 0 welcometojava 3 Sample Output 0 ava wel Explanation 0 S
