How to save web service request key and response value in cache to reduce calling the service for same type of requests

Question

Hi
I have a web service which return the response based on the request key.
I need to save the key and the response value in cache for around 30mins
 to reduce the web service calls for better performance.
Appreciate if any once can share a sample code

Answer 1

using System.Runtime.Caching;
public List<string> cachingwebserviceresponse()
{//Create a cache key
string strParameters = "1234";//Create a cache value holding object
List<string> results = new List<string>();//Create a cache
ObjectCache cache = MemoryCache.Default;//Assign key for the cache
string cacheKey = strParameters;//Check whether the key exists in the cache//If exists assign the values from the cache instead of calling the webservice//else call the web service and add the response to the cache
if (cache.Contains(cacheKey))
results = cache.Get(cacheKey);
else
{ //calling the web service client
using (service.webservice fd = new service.webserviceContractClient())
{ //Call the web service function to get the results
results = fd.DataSearch(strParameters);
} //Create the cache expiration policy. I have created for 30 minutes.
CacheItemPolicy cacheItemPolicy = new CacheItemPolicy();
cacheItemPolicy.AbsoluteExpiration = DateTime.Now.AddMinutes(30); //Add the response to the cache based on the key
cache.Add(cacheKey, results, cacheItemPolicy);
return results;
