Retrieve Header and cookie info from URL

[sherif]

Hello,
I have written an annonymous surfing application, the logic is simply sending the required URL to my site then the application there would retrieve the requested URL on "my server", change all the links and make a copy all the required files (pics,swf,js..) to "my server" then display it on my browser. The application is working fine.

The problem appears when the URL that I am requesting uses some header information like 'forms' info (e.g. logging on to my yahoo mail) or if the URL requires to put a cookie on the client's hard disk. I don't know where to read this data (URL header and cookie data) from. I am thinking If I could get it I would copy it to "my server" and resend it to the requested URL while navigating in its site. e.g. checking my yahoo email.

Is there a way to get that data ?
Thanks

if you want to get the headers, you will need to use fsockopen, and formulate your own http get and post requests for every page your wants, or the easier method, curl, also gives the option to return headers. curl will also manage cookies for you so you wont have to parse the headers to get the cookies.
