Hi,
I am in the middle of writing a CMS system and after reading and working through a few examples, I have settled on HttpHandlerFactory to perform what I need.
the key point is our sites are generally a mix of copy and registration processes. So I currently need to use the default HttpHandler for aspx to render the physical registration pages until I can work a way to content manage them too.
after creating the handler class I added the following to my website's web config
<add verb="*" path="*.aspx" type="Web.Helpers.HttpCMSHandlerFactory, Web.Helpers"/>
As the above path handles physical and cms driven pages, with a small check in the code I am able to see if the page physically exists and can then render the desired page.
public IHttpHandler GetHandler(HttpContext context, string requestType, string url, string pathTranslated)
{
string pageName = Path.GetFileNameWithoutExtension(context.Request.PhysicalPath);
context.Items.Add("PageName", pageName);
DirectoryInfo di = new DirectoryInfo(context.Request.MapPath(context.Request.ApplicationPath));
FileInfo[] fi = di.GetFiles("*.aspx");
var file = fi.Where(x => string.Equals(x.Name, string.Concat(pageName, ".aspx"), StringComparison.InvariantCultureIgnoreCase)).SingleOrDefault();
if (file == null)
{
return PageParser.GetCompiledPageInstance(string.Concat(context.Request.ApplicationPath, "/Default.aspx"), url, context);
}
else
{
return PageParser.GetCompiledPageInstance(string.Concat(context.Request.ApplicationPath, "/", file.Name), file.FullName, context);
}
}
The question I have is should I be using something other than PageParser.GetCompiledPageInstance when there is a physical page?
Update: since the above I have gone on to develop and HttpHandler for images, which again works on the same principle of if the image exists use it else serve from database. Had a bit of problem with png files but the below process works for the file formats shown.
byte[] image = null;
if (File.Exists(context.Request.PhysicalPath))
{
FileStream fs = new FileStream(context.Request.PhysicalPath, FileMode.Open, FileAccess.Read);
BinaryReader br = new BinaryReader(fs);
image = br.ReadBytes((int)fs.Length);
}
else
{
IKernel kernel = new StandardKernel(new ServiceModule());
var cmsImageService = kernel.Get<IContentManagementService>();
var framework = FrameworkSetup.GetSetFrameworkSettings();
image = cmsImageService.GetImage(Path.GetFileName(context.Request.PhysicalPath), framework.EventId);
}
var contextType = "image/jpg";
var format = ImageFormat.Jpeg;
switch (Path.GetExtension(context.Request.PhysicalPath).ToLower())
{
case ".gif":
contextType = "image/gif";
format = ImageFormat.Gif;
goto default;
case ".jpeg":
case ".jpg":
contextType = "image/jpeg";
format = ImageFormat.Jpeg;
goto default;
case ".png":
contextType = "image/png";
format = ImageFormat.Png;
goto default;
default:
context.Cache.Insert(context.Request.PhysicalPath, image);
context.Response.ContentType = contextType;
context.Response.BinaryWrite(image);
context.Response.Flush();
break;
}
