Use an HttpHandler to stop bandwidth leeching of your images

Parser Error Message: File or assembly name JpgHandler.dll, or one of its dependencies, was not found.

The error is on line 9, no other clues. My site did not have a "/bin" folder (off the root) so I created one, and copied my newly compiled dll "JpgHandler.dll" into that bin folder. I then added the above lines to my web.config. Then rebuilt solution. What am I missing?...anyone, anyone...Bueller...Bueller?

I dunno what's happening. I got rid of the errors. But the filter isn't working. For example I can cut/paste the URL into the browser and the image is still served up. Except for the domain name I pretty much cut and pasted this article's code verbatim. Weird. I'll keep playing around with it.

And locally. It does work sort of. When the page loads up the image is broken if it's not good referer (the no.jpg is not shown). And if I try to cut/past the url I get an error:
Could not find file "c:\inetpub\wwwroot\no.jpg".

Which doesn't make any sense because it should be looking for "c:\inetpub\wwwroot\mydomain\no.jpg".

The browser is probably caching it. I've had that happen to me, and checking in a new browser instance worked.

Thanks. The web host stop/started the services on the server and the custom HttpHandler started working. But about 12 hours later now it's not filter again. Appears to be something on thier end.

Regarding the HTTPHandler, is it possible to dynamically enable and disable the handler, through coding?

To be more specific, I need to have a web interface to enable the HTTPHandler and disable the same, instead of having an entry in the web.config file.

Is it possible?

Sure, from your web interface you could set the value of bool variable for examp;le. Then wrap your IHttpHandler logic in an If/Then type of statment.

IF boolUseHandler

THEN process the code block that serves up the requested image file name.

ELSE process the code block that servers up your leech.jpg

** Edit of bunch of code i posted **

Just a "gotcha" i ran across, i had:

it didn't work until i changed it to

httpHandlers>
verb="*" path="~/content/*.aspx" type="MapURL,__Code" />
httpHandlers>

then it worked...

now... i am just wanting to rewrite *.aspx requests in the root of the application, not of any aspx files one folder or deeper in the app, suggestions on doing this?

If you want to just work right out of the root, change the path to *.aspx.

In Whidbey, you don't have to reference the namespace of the dll. In v1.1, you do.
