web_url(“<HTTP call to the pdf file>”);
//Get the download size.
i = web_get_int_property( HTTP_INFO_DOWNLOAD_SIZE );

Problem Description: How to capture HTTP return code information
The user uses the following function to capture the return code of a webpage:
   HttpRetCode = web_get_int_property(HTTP_INFO_RETURN_CODE)
However, this function only captures the last status code that was received. If there is a redirection in between, it is not reflected. How can user detect redirection on a page?

Solution: Function to capture HTTP return code
To capture the HTTP returned code, you can use the web_get_int_property function.
Example:
HttpRetCode = web_get_int_property(HTTP_INFO_RETURN_CODE)
Note:
The web_get_int_property function only captures the last status code that was received. If there is a redirection in between, it is not reflected. To get all of the responses, you can use the web_reg_save_param function with:
1. The “ORD=ALL” attribute to capture all occurrence.
2. The “Search=Headers” attribute to search the response header only.
Example:
web_reg_save_param(“response”,”LB=HTTP/1.1 “, “RB= “, “Search=Headers” ,”ORD=ALL”, LAST);
