Raj R. Is it good idea to have try-catch in for loop for http requests?
Hi,
We have a need to keep sending HttpRequests to a particular endpoint until the server responds with a particular status code or if the endpoint is not available at all. We were thinking we can complish this by either doing a for loop or a do-while loop. When we make the HttpRequest we wanted to ensure that is done in a try-catch statement so that we can capture any callout exceptions appropriately.
Would it be advisable to do a try-catch in a for or do-while loop? I have yet to see any performance degradations but just wanted to be sure.
For loop example
Do-while example:

For loop example
//for loop
for() {
try {
HttpRequest request = new HttpRequest();
//build request by setting headers
HttpResponse response = http.send(request);
catch(CallOutException callOutEx) {
//handle exception
}
}//end for
Do-while example:
do{
try {
HttpRequest request = new HttpRequest();
//build request by setting headers
HttpResponse response = http.send(request);
catch(CallOutException callOutEx) {
//handle exception
}
}while(response.getStatusCode() == 200);
