How i can check private proxy anonymous level?

Hi, I have 10 dedicated private proxy bought from buyproxy. I want to test their anonymous level. I want to know if they are elite or anonymous. I asked customer support and they said they are elite but just for learning purpose i want to test their anonymous level myself. So in future if i change provider i do not need to ask again and again. I am not geek please tell me in simple language and step by step.
Please tell me all possible method to test anonymous level of private proxy.

And one more thing i want to know is what is proxy connect type. In the GSA ser in the proxy tab there is a option which show proxy connect type and it show all of my private proxy as Trans type and public proxy as Trans, Socks4, Web type. I asked sven developer of GSA ser and he told me "TRANS means it is a CONNECT type of proxy. It has nothing to do with how anonymous it is." Can somebody tell me more about proxy Connect type. How many connect type are there. Which should be avoid and which should be use?

Here is a ScreenShot of GSA ser Proxy Tab :


Thank You

Read this Wiki : http://en.wikipedia.org/wiki/Proxy_server#Implementations_of_proxies and http://ip.cc/proxy-classes.php to know difference between transparent/anonymous/highly-anonymous(elite) proxies.

I already know what is difference between Transparent, Anonymous and highly anonymous(elite) This is not what i ask. I asked how to check anonymous level of private proxy.

I wrote my own app.

It receives a request and dumps all the headers sent by the proxy so I can look at them. You can do this in PHP, just search for "headers dump in PHP" then you access that address using one of your proxies and you can see the headers. If it reveals your original IP then it's not anonymous.

Bartosimpsonio can you tell me any easy way to switch ip and test them with headers dump in PHP or i have to manually change ip in browser.

http ip . cc/proxy-classes . php
This is useful there is also Anonymity test option in the site so i put my proxy in firefox and visit this site and its telling my proxy are elite but i have 10 proxy so is there any easy way to check all the proxy in few clicks. What if i have 100 proxy i can't test by putting them manually so please tell me how i can test them without putting them manually in firefox and visiting this site.
Thanks

Try Proxyfire. It allows you to test the proxies and classify them as elite/anony/trans/socks and a lot more.

Go to from each of the proxies.

could test in charon or bleach both are free proxy testers

I did not find username and password option in charon. I want test private proxies and they require username and password for authentication or if there is option in charon for testing private proxy then would it be safe to test with it i do not want to upload my private proxy on charon server.

Sounds like you need someone to build you a tool.
