Hi There!
I'm writing a custom HttpHandler to create watermarks on my PNG images of my
website. So typically, a PNG image is linked in an ASPX page as follows...
<img src="images/test.png" alt="testing" />
So I created an HttpHanlder to handle PNG images, have mapped the PNG
extension in the IIS and also added the HttpModule section in the web.config
file.
In my HttpHandler's ProcessRequest event, I tried to retireve the Page URL
by...
context.Request .Url.AbsoluteUr i
But it is not returning the Page's URL but returning the URL of the PNG
image.
How can I retrieve the URL of the PAGE that links the PNG image?
Thank you all in advance!!!

Hi Vishnu,
Thanks for the help! But it didn't work out. I tried with the following
code...
context.Request .Path
It is still giving me the path of the PNG image and not the ASPX file path.
Any ideas?
Thanks again!

>added the HttpModule section in the web.config
typo??? You should be mapping the HttpHandler section in the web.config
since you wrote a handler and not a module.

Hello David,
You can not make this happen using the builtin objects, because as far as
the web server is concerned this is two completely separate requests, completely
independent of each other.
However, you could try passing the page name along as a parameter on the
query string. If you do that, make sure you test it for null though, because
if an image is direct-linked without the page name, you'll throw an exception
if you try and do anything with it.

Hi Dave,
I haven't tried, but the referrer should be what you're looking for :
Context.Request .UrlReferrer.Pa thAndQuery, for instance.

If you are interested in doing Url Rewriting with an HttpHandler
instead of an HttpModule, then this is the example for you. Suppose
you are deriving a piece of information from Url, like a product code.
To process it, you have a page that accepts the product code as a

I've got a custom HttpHandler to process all requests for a given
extension. It gets invoked OK, but if I try to do a Server.Transfer I
get an HttpException. A Response.Redirect works, but I really need to
avoid the extra round-trip to the client.
I've tried Passing the page name, the full URL, and the instance of
the handler class to the Transfer method, but everything gets me the
same error 500.
Any help would be appreciated.

Hi,
I have a problem of page redirection. Basically, the user has to connect to
the local web server, but some pages need to be served by a remote server,
because it contains some confidential data that cannot be moved locally
(everything occurs in the company Intranet, however). Since the ASP.NET
application uses extensive Javascript, we cannot make it work because of the
"cross-site" (same origin policy) of Javascript.
Therefore, we...
