HttpHandlers / Modules :: Generic Handler / Prevent Data From Being Written To Live Table Via The Live.aspx Page?
Jun 28, 2010
I am using a generic handler (indicator.ashx) to create a graphic that is overlayed from information from a table (called LIVE) from our SQL database. This is working very well and I am very happy with the results.
However I am having an undesirable issue where the query string that is used for this is also being accessed by another page (called ReceiveLive.aspx) which is populating our LIVE table with data when we don't want this. I have been able to track this issue down to our generic handler that seems to populate this table with data whenever the handler is accessed.
The query string that is used to access our graphic through our generic handler is
http://mydomain.com/indicator.ashx?ID=ABC001.
Our other page that writes data to our LIVE database used the query string
http://mydomain.com/live.aspx?ID=ABC001 which is normally only accessed by a small piece of software that sits on the users PC and sends the data when necessary.
My question is this: How do I prevent data from being written to our LIVE table via the Live.aspx page everytime a query string is processed by my indicator.ashx is accessed?

I wrote a generic handler like this:
[Code]....
and on the other page I would like to retrieve the database image using :
<img alt="" src="ShowImage.ashx?ID=467711" />
but I am getting nothing in this case. The picture exists and there are 91000 bytes in array.

I have an Handler.ashx file and on .aspx page load it calles the .ashx file for image reading. I am attempting to pass a session from the .aspx file to the .ashx file in order to make my query of grabing the image secure. The problem is that everytime I call a session: HttpContext.Current.Session["ID"], the value is returning null or errors saying the o so commong "Object reference not set to an instance of the object". I have tried a couple ways of grabing the session:
1.) context.Session["ID"]
2.) HttpContext.Session["ID"]
3.) HttpContext.Current.Cache["ID"]
none of them are giving me the ID session set in the .aspx page. should i be using Server.Transfer instead? is there a way to grab a session variable set in a .aspx page and called in a .ashx page?

Live Chat is a very famous tool on websites, and the operators use a special web/windows interface to talk to the clients.What I want to implement is to specify some email accounts, and when the client click's the live chat and starts typing, his/her instant messages are delivered to the available email account. My operators can talk back to them as if they are on their friends list.I don't need to require any login or registration for clients to use this Live Chat.So are there any ideas about how to implement such a thing? Are there any good third-party-modules that already do that?

I have a form with a server side button, clicking on which session variable is added Session.Add("ABC","123")After this (in same postback event), I redirect user to a site, which returns user back to my site. And I still have session "abc" available to me.NOW, In another scenario I am trying to do the same thing but in a handler. I.e.User clicks a clinet side button which redirects users to sameSite.xyz. Handler of xyz adds session variable like above and redirects user to the other site. But, this time when user returns back from other site, my session is lost. How can I imitate scenario 1 with handlers?

I have 50 sites for 50 states. When a company uploads their contact info their image is stored in a folder relative to the site they are uploading from. When you view this company on the other sites the image is not present. So, I was thinking I would store the path of where the file is originally and then access it through the handler, but I can't seem to get the handler to recognize locations other than virtual directories.

a silverlight app sends an image to a webservice which store the image in a database and then a handler retrieves the image from the db to display it... quite common so far.
Everything is working absolutely fine on my test server (IIS on my development machine) but, as soon as i try it on the production server : no way, the image is never displaying (in any browser). Firefox says that it cannot display it because it contains error...
I tried to download the database from the production server just after saving an image to the db and, locally, the image is displaying...
The image is in png format.
Here is my code :

I have a HTTP handler that returns a GeoRSS feed (type of XML) when called. This handler is called from a javascript and the returning xml is consumed directly by a Virtual Earth (bing) map control on the same page. I am Encrypting/Decrypting URL parameters but any one can see the source html, copy the url and get access to the xml feed.Since the call is from javascript how can I prevent unauthorized access to the HTTP handler?

i have a custom handler which captures user's book mark entry. To debug this handler, i have created a file "test1.txt" in code behind which saves the user entry. After the debug, i removed the text file (test1.txt) then re-complied the web app and deployed new DLLs for the site. But, the site is still looking for test1.txt file. i dont know how to confirm if the handler is really removed from the new DLL. Also, looked at the handler code behind file and didn't find any entry with test1.txt. So,

The iPhone sends an HTTP GET request to my web application to recieve an update for an internet calendar. The iPhone does not conform to the RFC 822 Date Format for this request. It sends the If-Modified-Since as follows:
RFC 822 format - Sun, 06 Nov 1994 08:49:37 GMT
iPhone Format - Sun, 6 Nov 1994 08:49:37 GMT
I dont know much about handlers or modules. Is it possible to write a handler or module that could intercept this request and reformat the If-Modified-Since date format to the standard. Currently when IIS recieves this request it immediately sends back a 400 Error because of this invalid format.
