HTTP headers

I would like to know the some or the other details about the HTTP headers. I am not having more details on it, and would like to know this for my own reason. If anybody is having details about it, then please give me that. It will be helpful to me. Thanks in advanced.

If you would like to get back the HTTP Headers then you can get that with the use of the Constant as below:

• using the HttpQueryInfo function for receiving the HTTP header using the constant follow the steps given below:

• Initial it is required to call the HttpQueryInfo by the use of the feature list, a NULL buffer, and the variable which gets buffer size set to 0. For specific format data you can just use the constant from the modifier list.

• If the header which is request exists then call to HttpQueryInfo should fail and GetLastError should return ERROR_INSUFFICIENT_BUFFER and the parameter which is agreed for the lpdwBufferLength set to the bytes required.

• Now you want to place the buffer with the total bytes necessary.

• Now you can try over again for calling the HttpQueryInfo.
