Fetch data from HTTP events

You can collect data from both HTTP request and HTTP response events. You can then manipulate this data.

Fetch data from HTTP events:

when HTTP_REQUEST{
--HTTP:collect command can be used in both HTTP_REQUEST and HTTP_RESPONSE events
--size is optional, otherwise, it will collect up to the full length or when 1.25M is reached
t={}
t["size"] = 100;
HTTP:collect(t)
}

when HTTP_DATA_REQUEST{
--check the size of the content
t={};
t["operation"]="size";
sz=HTTP:payload(t);
debug("content size: %s\n", sz);
--fetch the collected content
--offset and size are optional
t={};
t["operation"]="content";
t["offset"] = 0;
t["size"] = sz;
ct=HTTP:payload(t);
debug("content: %s\n", ct);
--do your own manipulation on the collected content
--replace the collected content by your new data
--offset and size are optional
t={};
t["operation"]="set";
t["offset"] = 0;
t["size"] = sz;
t["data"]="NEW DATA to SEND";
ret = HTTP:payload(t);
debug("set ret %s\n", ret);
}
