AJAX :: Comet - Detect If The Client Disconnected During Those 10 Minutes?
Jan 29, 2010I implemented a chat using the COMET "way" described in this article: http://www.codeproject.com/KB/aspnet/CometAsync.aspx
In this example, the client connects for 5 seconds every time. I wanted to hold the client longer, for about 10 minutes.
My problem is - how to detect if the client disconnected during those 10 minutes? I tried using Response.IsClientConnected but it returns true even if I close the client. There must by some inidicator since the socket gets disconnected if I close the client.
AJAX :: WebResource Fail To Work Under Reverse Proxy?
Jul 19, 2010We have an issue when our web application runs under reverse proxy.
The reverse proxy change the URL for the website from for example: "http://TestWebApp/" to: "http://ProxyDomain/Test/" when it runs under reverse proxy which is mapped to "http://TestWebApp/" and rout requests to it.
This raise an issue of root relative paths (paths that start with "/" to be relative to the root of the web application i.e. "/Folder1/Test.aspx"). Generally all paths that need to be rendered to client we use ResolveClientUrl method and all is good.
When using Ajax controls and ScriptManager WebResource.axd paths are rendered in script tags as a relative url paths ("/WebResource.axd?blablabla") because the root under reverse proxy is the proxy domain itself the path is useless - the web resouce is not downloaded and the application break.
To fix this we tried to set a Response.Filter in OnPreRender event handler of our base page. In our custom filter we use Regex to search and replace all "/WebResource.axd" occurences with the resolved to client root path using the ResolveClientUrl method of the page. This works great and the web resources are downloaded to client.
But this is not the end of our troubles.
In Ajax requests the response output is fixed as described but when recieved at the client end it is not valid and the partial update fails with Sys.WebForms.PageRequestManagerParserErrorException.
It fails to parse the response because the rendered response have numbers that states the actual count of bytes per rendered component (which includes the script tags referencing the WebResource.axd). The client reciever validates the recieved response according to the numbers, but, our filter altered the response so the numbers are not correct and the response validation fails.
We can try and code a smart filter that parse the response and recalculate the numbers according to the ammount of paths fixed, but I hope there is an elegant and better solution for this.

AJAX :: AutoCompleteExtender Implementation Guidelines
Jun 1, 2010use a textbox and the AutoCompleteExtender to search for the customer. For example, on the PurchaseOrder form, I have a textbox with a Customer field, and when I type in the name of the customer, the AutoCompleteExtender shows the possible matches.Now, it takes a few seconds to show the list of values, even with setting the correct values on the extender, and if the user types in the name of the company, e.g. Contoso, and leaves the textbox, there might be 2 Contoso's in the database. The AutoCompleteExtender does not continue when the user leaves the textbox, thus the CustomerId is not determined yet.

View 1 RepliesAJAX :: Implementation Of Seadragon And Preloading Images
Oct 4, 2010I've been implementing Seadragon (as part of the ACT), but have recently found some users complaining of slow speeds whilst using it - I thought this odd because the whole idea of Seadragon and DeepZoom is streaming images as they're required rather than loading one huge image in one request.
I've done a bit of testing (using Firebug) on both our web pages and the ASP.net ACT Sample website Seadragon control, and have found that when the control is opened on screen, the browser decides to load all the tile images at once (even the tiles which aren't at the default zoom level).
Has anyone else experienced this and does anyone know why it does it/if there's a fix? The fact it happens on the ACT sample site has left me tearing my hair out because I know that it's not just my implementation of the control that's causing problems.

View 3 RepliesC# - Comet Pushing Messages From Server To All Clients
Aug 23, 2010I'm making an application with server sided variables that change every second. Every second those new variable need to be shown at all the clients that have the webpage open. Now most people told me to go with comet because I need to push/pull the data every second, now I've got a few questions: What would be a better solution looking at the fact that I need the new data EVERY SECOND, pulling from the client or pushing with the server?
Also the item ID's that are on the server side (with the variable's that ID got) can change and when the client refreshes the page he needs to get the oldest (and living) ID's. This would mean that my jquery/javascript on the client side must know which ID's he got on the page, what is best way to do this? Last thing is that I can't find a good (not to expensive) comet library/api for asp.net (C#). Anyone ever used a comet library with good results? We're looking at a site that should be able to have 2000 comet connections at every moment.

Enable Reverse DNS Lookup For IIS?

I'm trying to enable full DNS lookup including hostname. Having trouble. I've followed the instructions here
(http://support.microsoft.com/kb/297795) with no luck. Request.ServerVariables("remote_host") still returns only an IP Address.
[Code]....
I've also tried using DNS.GetHostEntry(IPAddress) and the depricated DNS.GetHostByAddress(IPAddress). All I ever get back is the IP Address with no host name.

MVC :: Reverse Proxy And Authentication?
Feb 21, 2011We have nearly completed an ASP.NET MVC web application running with SSL in IIS and now find that we must integrate with a third-party product that is supplied as a PHP web app running under lightppd on an alternate port, but still on the same server.
We want to make the integration appear as seamless as possible, so our initial strategy is to do all of the authentication through our application, implement a reverse proxy to expose selected features from the third-party product, and then set-up the third-party product to only be accessible from localhost and (if we can manage it) only from the user our app pool runs as. As a second layer on top of this, we plan on running the third party active content in an IFRAME, so we can surround it with our menus and headers. With the right fonts and colors, hopefully, it won't look grossly out of place.
First question: Is this strategy totally naive? Given the hand we've been dealt, is there a better one?
Second question: What is the best way to implement the reverse proxy? I was thinking of using a routing rule with an Http Handler that invokes our usual authorization just as a controller would and makes the requests to the other site, streaming out the results it receives. Is there something that already does this generically, that I can just hook up and invoke? Maybe some way to specify a controller to handle everything I need to proxy and then use a ViewResult that represents a call to an external URL I construct from the URL I received?
If I can get a few pointers on what to look for, I can trot off to the docs for the details.
