Add page size funcion code into your LR scripts

As my ramp up project, I spent some time to complete a sample on how to get page size after applying small piece of code

Choosing Ajax(click and scripts) protocol；
pre-condition： set your log level as "send message only when an error occurs"
Within globe()
set one flag to trigger the page size func code on demand:
int flag=0;

Within vuser_init()Action, you can initial such parameter as:
lr_save_int(0, "accu_google_frontpage_PageSize");

Within Action() i take google landing page as a example:

int ThisTimeHttpResponseSize=0;
char *message;
int i=0;
int loops=2;

lr_save_int(loops,"loops_goo");

 while(i小于loops){//if there is some loops here

  message=(char *)malloc(140*sizeof(char));

  memset(message, 0, sizeof(char)); 

  web_browser("www.google.com", 
  DESCRIPTION, 
  ACTION, 
  "Navigate=http://www.google.com/", 
  LAST);

  i++;
 
  if (flag==1) {//enable pagesize func, if flag==1;
  
   lr_set_debug_message(LR_MSG_CLASS_JIT_LOG_ON_ERROR, LR_SWITCH_OFF);
  
   //web_get_int_property Returns the accumulated size, including header and body, 
  
   ThisTimeHttpResponseSize = web_get_int_property(HTTP_INFO_DOWNLOAD_SIZE);
   
   strcat(message, "PageSize_of_google_frontpage_");
   strcat(message, lr_eval_string("{Iteration}"));
   strcat(message, " = %d");
   lr_message(message, ThisTimeHttpResponseSize);
  
   lr_set_debug_message(LR_MSG_CLASS_JIT_LOG_ON_ERROR, LR_SWITCH_ON);
  
   //multiple iteration accumulated
   lr_save_int(atoi(lr_eval_string("{accu_google_frontpage_PageSize}"))+ThisTimeHttpResponseSize, "accu_google_frontpage_PageSize");

  }
 
 free(message);

 }

within end() action, calculate the average number of each page size:

if (flag==1) {

 lr_save_int(atoi(lr_eval_string("{Iteration}")), "Iterations");
 lr_set_debug_message(LR_MSG_CLASS_JIT_LOG_ON_ERROR, LR_SWITCH_OFF);
 lr_message("Iterations=%s",lr_eval_string("{Iterations}"));
 lr_message("Avg_google_frontpage_PageSize = %d", atoi(lr_eval_string("{accu_google_frontpage_PageSize}"))/(atoi(lr_eval_string("{loops_goo}"))*atoi(lr_eval_string("{Iterations}"))));
 lr_set_debug_message(LR_MSG_CLASS_JIT_LOG_ON_ERROR, LR_SWITCH_ON);

 }

So you will get each page size freely now!

Thanks my friend Jeff,Alfred and Calvin previous sample code and ideas!
