Capture correlation value from response headers | CsrfToken Value Correlation

To capture the csrf token value in headers you need to do one thing prior to enhance the script.

1. Go to Recording Options
2. HTTP properties
3. Advanced
4. Headers and add 'csrf-token' or select 'Record header not in list'.Then record the script or regenerate the script.

Please note that the header name in web_add_header is without the colon (:) or space. The right boundary in web_reg_save_param function should be \r\n 

web_add_header("csrf-token","{CsrfToken}"");

In header server response the token value looks like this
x-csrf-token: 0FTwrefb89ijdhdhky0lkdkdkkrelw0rIw==

The final function should be as follows

web_reg_save_param("XCsrfToken","LB=x-csrf-token: ","RB=\r\n","Search=Headers",LAST);

How to capture whole body of Web page with Load runner Vugen?

Sometimes there may be a requirement to capture whole web page body and here is the code for this.

int MyFile;
char *TargetFileName = "C:\Users\pc\Desktop\Webpage.html";
Place web_reg_save_param before the web_url

web_url("EasyLoadrunner",
"URL= https://easyloadrunner.blogspot.com/",
"Resource=0",
"RecContentType=text/html",
"Referer=",
"Snapshot=t11.inf",
"Mode=HTML",
LAST); 

left and right boundaries should be empty to capture the whole body

web_reg_save_param("WholeWebPage", "LB=", "RB=", "Search=Body", "RelFrameID=1", LAST);

Now write the captured web page in to a file

lr_output_message("Page is: \r\n%s", lr_eval_string("{WholeWebPage}"));

Truncate to zero length or create file for writing the whole page

if ((MyFile = fopen(TargetFileName, "wb")) == NULL)
{
lr_error_message("Cannot open %s", TargetFileName);
return LR_FAIL;
}

print the captured Web page to an output file

fprintf(MyFile, "%s", lr_eval_string("{WholeWebPage}"));
fclose(MyFile);
