Comet Programming in IIS

爱⌒轻易说出口 提交于 2019-11-29 21:19:00
问题 It is said that IIS is not recommended for Comet programming. If that is true, how is it that other web servers are able to handle this vis a vis IIS. So what is it that other web servers do additionally which allows them to scale out. 回答1: For some reason, this myth is still around. It's certainly possibly to do this with IIS, as demonstrated in our IIS-based comet server, WebSync. The myth started with standard ASPX pages (which, if you hold open, will crap out around maybe 100 or so

how to combine django plus gevent the basics?

馋奶兔 提交于 2019-11-29 20:30:02
After much searching and googling I am coming back to the well. I have Django 1.4 and am looking for a decent working example to figure out getting Django to work with gevent. I like the Django framwork but I need it to handle long polling. I already have a working server using gevent on it's own that handles long polling requests as well as does image streaming via http at about 10 frames/second. I would like to use all the goodies in Django to provide a framework for this part. There are many examples out there, but unfortunately none of these seem to work out of the box! It would really

How do I use Django with the Tornado web server? Moayyad Yaghi it's very simple ( especially with django 1.4) . 1 - just build your django project( and apps ) and make sure it works fine. 2- create a new python file at the root folder ( same dir where you used django-admin.py startproject ) 3- then copy the code below , edit the os.environ['DJANGO_SETTINGS_MODULE'] line, and paste it in that new .py file. import os import tornado.httpserver import tornado.ioloop import tornado.wsgi import sys import django.core.handlers.wsgi #sys.path.append('/home/lawgon/') # path to your project ( if you

Apache with Comet Support

I'd like to build a multiplayer web game application in which it supports chat. I presume the application will have to handle hundreds of simultaneous connections. I'm planning to host my application in a shared web hosting, which has these limitations (most likely similar to PHP + Comet (long-polling) scaling / hosts ): It does not seem I can change the web server. Most likely it's using Apache. Supports MySQL 5, PHP 5.3.x, Perl, Python, Ruby on Rails, CGI (To be more precise, I'll be using HawkHost's shared web hosting.) And here are my result of research, followed by my questions: Some

Is Http Streaming Comet possible in Safari?

与世无争的帅哥 提交于 2019-11-29 12:46:00
问题 By HTTP Streaming Comet, I mean the "forever iframe" / "forever xhr" variations that don't close the connection after data has been pushed from the server, as opposed to standard polling and long polling which close and resend a new request for every server push event. I looked at the dojo.io.cometd package and it seems they only have polling implementations. I also found this example, but it doesn't seem to work in webkit even after a fair bit of tinkering (I got it to work everywhere else).

How To Implement ReverseAJAX (Comet) in ASP.Net MVC

问题 How could I implement a Comet architecture in a ASP.Net MVC? 回答1: The paid alternative There are great comments about the question in this thread. And based in the fact you can use handlers in a MVC app: WebSync will do the work : ) 回答2: As long as you need to implement server push support onto your ASP.NET MVC application you will need some extra functionalities like detection of client status etc. I suggest you to try PokeIn comet ajax library which you can find sample project here 回答3: I

GWT / Comet: any experience?

怎甘沉沦 提交于 2019-11-29 01:12:04
问题 Is there any way to "subscribe" from GWT to JSON objects stream and listen to incoming events on keep-alive connection, without trying to fetch them all at once? I believe that the buzzword-du-jour for this technology is "Comet". Let's assume that I have HTTP service which opens keep-alive connection and put JSON objects with incoming stock quotes there in real time: {"symbol": "AAPL", "bid": "88.84", "ask":"88.86"} {"symbol": "AAPL", "bid": "88.85", "ask":"88.87"} {"symbol": "IBM", "bid":

Indicate to an ajax process that the delayed job has completed

元气小坏坏 提交于 2019-11-28 21:52:15
I have a Rails 3 app that uses delayed_job to fetch some data (with a class method) when the user hits the page. How can I indicate to the ajax process that the class method has run (so that I can stop polling)? EDIT: To clarify, I want to know when the delayed_job has run, not when the ajax process has succeeded. Then I want to pass the delayed_job completed status to the running ajax process. Typically, the best way to do this is to store, in your database, an indication of the job's progress. For instance: class User def perform_calculation begin self.update_attributes :calculation_status =

How to implement Comet server side with Python?

折月煮酒 提交于 2019-11-28 20:58:42
I once tried to implement Comet in PHP. Soon, I found that PHP is not suitable for Comet, since each HTTP request will occupy one process/thread. As a result, it doesn't scale well. I just installed mod_python in my XAMPP. I thought it would be easy to implement Comet with Python asynchronous programming. But still cannot get a clue how to implement it. Is there any idea how to implement Comet in mod_python? First of all, I'm not async expert at all, I just investigated the topic once. IMHO if you're using XAMPP then you're loosing the posibility of doing long polling because Apache uses

How does GMail implement Comet?

With the help of HttpWatch, I tried to figure out how GMail implements Comet. I login in to GMail with two accounts, one in IE and the other in Firefox. Chatting in GTalk in GMail with some magic words like "WASSUP". Then, I logoff both GMail accounts, filter any http content without "WASSUP" string. The result shows which HTTP request is the streaming channel. (Note: I have to logoff. Otherwise, never-ending HTTP would not show content in HttpWatch.) The result is interesting. The URL for stream channel is like: https://mail/channel/bind?VER=8&at=xn3j33vcvk39lkfq ..... There is no surprise
