Hi Shrikant,
That dosen't solve my problem.
I have code as mentioned below: Any help would be much appreciated. Thanks
public class CachingHandler : IHttpHandler
{
public bool IsReusable
{
get { return true; }
}
//public ArrayList ChangeImagesFileName = new ArrayList();
public void ProcessRequest(HttpContext context)
{
//string file = context.Server.MapPath(context.Request.FilePath.Replace(".ashx", ""));
string file = context.Server.MapPath(context.Request.FilePath);
string filename = file.Substring(file.LastIndexOf('\\') + 1);
string extension = file.Substring(file.LastIndexOf('.') + 1);
//Get Last Modified Time of Image file
//FileInfo fileAttributes = new FileInfo(file);
//DateTime dt = fileAttributes.LastWriteTimeUtc;
CachingSection config = (CachingSection)context.GetSection("CachingHandler/Caching");
if (config != null)
{
//if ((dt - DateTime.UtcNow).Hours > 48) //Retrieve from cache only if file is not modified in last 48 hours.
//{
context.Response.Cache.SetExpires(DateTime.Now.AddHours(config.CachingTimeSpan));
context.Response.Cache.SetCacheability(HttpCacheability.Public);
context.Response.Cache.SetValidUntilExpires(false);
//}
//else
//{
// context.Response.Cache.SetExpires(DateTime.Now.AddMilliseconds(0));
// context.Response.Cache.SetCacheability(HttpCacheability.NoCache);
// //Remove from Caching because Image is modified in last 48 hours.
// context.Response.Cache.SetValidUntilExpires(true);
//}
FileExtension fileExtension = config.FileExtensions[extension];
if (fileExtension != null)
{
context.Response.ContentType = fileExtension.ContentType;
}
}
//Get Last Modified Time of Image file
FileInfo fileAttributes = new FileInfo(file);
DateTime dt = fileAttributes.LastWriteTimeUtc;
if ((dt - DateTime.UtcNow).Hours > 48 && filename.Substring(0, 4).ToUpper() != "USER") //Retrieve from cache only if file is not modified in last 48 hours.
{
context.Response.AddHeader("content-disposition", "inline; filename=" + filename);
context.Response.WriteFile(file);
}
else
{
context.Response.AddHeader("content-disposition", "inline; filename=" + filename);
context.Response.WriteFile(file);
}
}
