    proxy questions

    How come I keep dropping proxys ? If I enter the proxy to use in the browser it only lasts for a few minutes. The other day I went through 8 proxys in 16 minutes. They work for a short time then stop working. I understand the level rating and the different types of proxys. Knowing that does not answer a few more questions.

    How many other users can a proxy handle ?

    How many connections can a proxy handle ? Besides the listing that says it can handle a type of connection. Are there any commands that will bring up the proxy commands list ? Or info about that proxy ?

    Why will a certain search engine return “we do not take automated requests” while using a proxy when that is the job of that certain search engine to search for what ever that request was for ?

    how come the proxy does not return most third party pictures ? It seems that the proxy will return pictures that are hosted on the web page but not all third party pictures ? That as I understand is the job of the proxy to “fetch” the web page and return it to the browser using the proxy. Guessing that the third party pictures are sent to the proxy it should then send them to the browser and user using the proxy ? Is something else going on with the picture transfer ? I understand that the third party pictures are hosted on another site repository but in theory <were that went wrong> should return the pictures to the requesting proxy ip. Then transfer them back to the browser behind the proxy.

    Know of any example code in c of a proxy ? tia

    proxy hairball meow ?

    That is implementation specific. Proxies drop innactive connections. the socket stack will also drop an innactive connection after a usually longer time. Somethign like 10 minutes.

    How many other users can a proxy handle ?
    That is implementation specific, btu technically thousands, although the bandwidth fo its network will saturate before it hits the actual limit usually.

    How many connections can a proxy handle ?
    Implementation specific but see above.

    Besides the listing that says it can handle a type of connection. Are there any commands that will bring up the proxy commands list ? Or info about that proxy ?
    Entirely implementation specific, refer to your proxy manual.

    Why will a certain search engine return “we do not take automated requests” while using a proxy when that is the job of that certain search engine to search for what ever that request was for ?
    To prevent denial of service attacks and to thwart third party spiders from building a comprehensive database for free. BTW this is actually how Google operated in the beginning, it merely compiled the results from a dozen or so other search engines. So it's actually kind of hypocritical of them to not allow new startups to use them that way, but hey thats business.

    Thats a proxy setting in the proxy software itself.

    A quicky Google search didn't turn up anything promising, but maybe a more thorough look will reveal the apple of your eye.
    Until you can build a working general purpose reprogrammable computer out of basic components from radio shack, you are not fit to call yourself a programmer in my presence. This is cwhizard, signing off.

    Would that help? idk.

    I am not talking about just dropping the connection although that does happen a few times. I am talking about the public proxy on another machine stops working altogether. No “proxy is refusing connections” messages like I sometimes get. When I checked the proxy list again the list said “0 listings” There was 8 listed before. I used all of them. As I understand those proxies were on machines all around the globe and not on the same server. Checked back <with the proxy lists> many times before and tried many other proxies with the same nonfunctioning results.


    sure I can chain many proxies together with the proggies that I compiled but getting it to work with a browser <firefux> . Clicked tools options advanced”configure how firefux connects to the internet”settings then radio button “manual proxy configuration” and enter the ip of the proxy to use. Easy. And the port number.

    Entirely implementation specific, refer to your proxy manual.
    implementation is to browse web pages. I have NO proxy manual meow. I did download a few free proxy progs but when I ran them through a scanner they came back with the error”.exe -> Proxy.Delf.bm “ unsure what that is the prog was not run. I know what a proxy is but it is the delf.bm that is unknown part. I had other proxies that I played with a long time ago. Could not find them.

    I can download proxies to install on this box not a problem. I believe that I will have the same issues as the open proxies.

    If I had to reverse engineer a proxy I would think if it like a standard server that modifies the header in the packettes as if it were the requesting machine instead of just passing the packettes to the destination machine. Then pass the response back to the real original requesting machine.

    Thats a proxy setting in the proxy software itself.
    but the pictures seem to be intermittent and unpredictable if they will show up or not. Add that the proxies are slow too. Slower than a standard server passing packettes to the destination machine and back. Much slower.


    that was the point of using a proxy to search ga ga ga ga geewwwwggle. There are few isssuess like them pushing their advertisements on to each page you pull up. As I recall it was a virus like pusher that inserted their adds on to every web page and hard to get rid of. Then their tracking cookies from the main search engine not the vendors or listings. Their openid is an exploit waiting to happen. Oh whait that iz the exploit. Mostly it is the data base of your search habits. Privacy ? Then taking over other companies can be both good and bad for the public. Not allowing proxies to be used to search with means there is some kind of information collection going on.

    To prevent denial of service attacks and to thwart third party spiders from building a comprehensive database for free. BTW this is actually how Google operated in the beginning, it merely compiled the results from a dozen or so other search engines. So it's actually kind of hypocritical of them to not allow new startups to use them that way, but hey thats business.
    kinda like microandsoft making you “register” every os from them.

    back to the proxy issues. Rereading the wiki pages on proxies to see if I could come up with a reason they were dropped non working. I did not do anything unusual. Still confounded.

    I will stay with the free proxies thank you.
