Long time ASP.NET Webforms developer, new to Ajax development (mostly via the UpdatePanel control !). Since no postbacks are happening the server does not reset the user’s session timeout counter, even though a user is interacting with a page and refreshing parts of it. I would like to know what is the simplest and standard way of keep...
I am making an http request which ends up taking more than 8 mins. For me, this long running request work fine. I am able to get a response back to my browser without any issues.

Here is something I am trying desperately to get to work: I have an app that polls the GPS module in specified intervals and then sends out coords out to a server using Unix calls such as write(); It works fine when the app is active, but once the screen locks itself, reporting stops.

Im trying to grab all data(text) coming from a URL which is constantly sending text, I tried using PHP but that would mean having the script running the whole time which it isn’t really made for (I think). So I ended up using a BASH script. At the moment I use wget (I couldn’t get CURL to output the text to a file) wget --tries=0 --ret...

Hello, I would have question regarding web services. Let's say I have webservice client that has to perform under high load. And I cannot use another technology.

I have a one page web app so there is no page refreshing. Sometimes I leave the page open overnight and I come back in the morning and start interacting with it again. Usually I find I have to refresh. Javascript performs incorrectly - edit-in-place loads weird data, ajax calls don't fire... It's nothing to do with the backend, it seems ...
Hi. I need a python http client that can reuse connections and that supports consuming the stream as it comes in. It will be used to parse xml streams, sax style. I came up with a solution, but I'm not sure it is the best one (there are quite a few ways of writing an http client in python) class Downloader(): def __init__(self, h...
I have a few web servers behind an Amazon EC2 load balancer. I'm using TCP balancing on port 80 (rather than HTTP balancing). I have a client polling a Web Service (running on all web servers) for new items every few seconds. However, the client seems to stay connected to one server and polls that same server each time. I've tried usin...
At work, we have a client-server system where clients submit requests to a web server through HTTP. The server-side processing can sometimes take more than 60 seconds, which is the proxy timeout value set by our company's IT staff and cannot be changed. Is there a way to keep the HTTP connection alive for longer than 60 seconds (preferab...

But the report generation sometimes takes a lot of time, and the web request times out through the intermediate proxy server.(Timeout :90 secs). The workflow for downloading the report is straightforward. Client sends request to the web server. The web server generates the report ,...

How is this value used by the Web servers? is this value just set on the underlying TCP/IP socket i.e is the HTTP ...

Is it possible to disable Keep-Alive on a directory basis? For example, I have an API that runs on something like domain.com/api/ It'd be nice if KeepAlive was not used on any requests in the /api/ directory.
