is it somehow possible via function module or class/method to check if a given URL is valid ?
in MSS i display photos of employees from intranet-server of customer:
for example:http://www.intranetserver.com/Employees/12345678.jpg -> 12345678 stands for the personnell number.
Some employees don't have a photo, so the url can't be found as there is no photo on intranet-server. When put the URL into browser i get error 404 (page not found) back.
but how can i check if this URL is valid inside abap-coding ? i have to do some other coding when url does not exist, and i need this before.
