What % of traffic is network overhead on top of HTTP/S requests

问题 If we: 1) Count bytes/bits at the network adapter level (raw # of bits through the NIC) and, 2) Count bytes in all HTTP/S request/responses. Assuming only HTTP/S traffic is on the box, and assuming a statistically relevant amount of "typical" web traffic: I want to know about how much more traffic will be counted at the NIC level than at the HTTP/S level (counting http headers and all) because of the extra network overhead. 回答1: You have zero knowledge about the layers below HTTP. You can't

Google Analytics cookies vs subdomain for static content

社会主义新天地 提交于 2019-11-30 12:41:39
I have a website on www.example.com and use Google Analytics. I've also set up static.example.com which serves all static content. The problem is that the default behavior of GA is to issue cookies on ".example.com" but I don't want the static content traffic to be carrying the weight the GA cookies. I tried pageTracker._setDomainName("none"); and it worked well for the cookies problem but it completely messed up the "Avg. Time on Site" report (from 5 mins average it went to 40 mins until the day I reverted the _setDomainName call). Any idea why this is happening and how could I fix it? The

Determining an 'active' user count of an ASP.NET site

北慕城南 提交于 2019-11-29 15:05:54
问题 On an ASP.NET site, what are some techniques that could be used to track how many users are logged in to the site at any given point in time? So for example, I could produce a report showing something like this: 10:00am 11:00am 12:00pm 1:00pm 2:00pm .... 3/25 25 32 45 40 37 3/26 31 38 50 57 40 3/27 28 37 46 35 20 etc. EDIT: No, we're not using ASP.NET Membership provider, it uses a home-grown/hacky session based method of determining whether or not a user is in 'logged in' status. 回答1: Does

how to handle 2000+ requests/sec on tomcat?

本小妞迷上赌 提交于 2019-11-28 03:16:36
I am developing an SMS application in Java. My clients send queries via SMS which will be forwarded to my server in the form of http requests through SMS Gateway. Now my app processes the requests and sends back responses to clients again through SMS Gateway. Maximum only 300 characters are sent as response. I'm expecting very high traffic (2000 requests/sec). I wanted to host my application with some webhosting company (considering mochahost). What factors should I consider before hosting (interms of RAM, CPU, etc) and also what shall be the major bottlenecks? Can dedicated tomcat server

How do I dynamically load Google Analytics JavaScript?

社会主义新天地 提交于 2019-11-27 12:11:47
Without using any other JS frameworks (dojo, jquery, etc), how would I dynamically load Google Analytic's javascript to be used on a web page for web-tracking? The typical appropriate to dynamically loading JS is to do the following: var gaJs = document.createElement("script"); gaJs.type = "text/javascript"; gaJs.src = "http://www.google-analytics.com/ga.js"; document.body.appendChild(gaJs); var pageTracker = _gat._getTracker("UA-XXXXXXXXX"); pageTracker._initData(); pageTracker._trackPageview(); But that doesn't work. The ga.js file isn't loaded in time for _gat._getTracker & _initData

What are the advantages of using CSS Sprites in web applications?

淺唱寂寞╮ 提交于 2019-11-27 03:14:42
问题 I'm working on a website with reasonably heavy traffic and I'm looking into using a CSS sprite to reduce the number of image loads in its design. Are there any advantages to using a CSS sprite besides reducing the amount of transmitted data? How much space do you really save? Is there a threshold where using sprites becomes worthwhile to a website? UPDATE: Thank you for your responses. They are obviously all very carefully thought out and present good sources to verify your points. I feel
