How do I send multiple requests at one time?

Michael | Last updated: Apr 28, 2015 04:47AM UTC

I want to take a single request, let's say a POST request to google.com. I want to send, let's say, five requests almost parallel with each other.

You can do this with Intruder by configuring multiple request threads. You can use the "Null payload" option to make Burp send the same base request over-and-over without modifying it.

This is a known issue with Intruder in that the payload marker character cannot be used literally within the request. We chose this character because it does not normally appear within HTTP request. The exception is one with binary content in the body, which can of course contain anything. In this event, you'll need to either edit the message body to get rid of the character or use a different tool.

This does not work if the request is multipart/form-data with a binary attachment. The Intruder will try to interpret the § symbols in the binary data as payload positions, destroying the binary file.

Usman - In that case you probably want to turn Intercept off. That will let you browse normally and Burp will capture the request history. You can then send requests from the proxy history to other Burp tools, such as Repeater and Scanner. If you do want to use Intercept, but for it to only trigger on some requests, look in Proxy > Options > Intercept Client Requests, where you can configure interception rules.

Hi! When I browse any website with burp proxy on I have to press forward button multiple time to load the page. Now I want to browse each functionality of target website manually as in normal browsing with proxy intercept remain on. Kindly let me know that how i can browse normally and still intercept all requests in history. Thanks
