  • NotImplementedError with latest Jython release

    The following change for the latest Jython release might break some UI-centric extensions: "Abstract methods of an inherited class or interface from Java now raise NotImplementedError, instead of returning None (in Java, null) or some "zero", if they are not implemented in the extending Python class." source: As described, if your Burp e...

  • IRequestInfo getHeaders

    Why does the getHeaders method return a list<String> instead of a HashMap<String,String>. I think that everyone using getHeaders is now doing extra parsing on the list of strings since the normal usage would be something like this: headers = info.getHeaders(); String content-length = headers.get("content-length"): The List<String> is really unpractical and I am c...

  • IExtensionHelpers.makeHttpRequest() with cookies

    It appears that IExtensionHelpers.makeHttpRequest(URL) does not include session cookies in the resulting request. How can I construct a GET request that includes the session cookies? Is there a helper method to get all the appropriate cookies for a particular domain/path?

  • getComment() not returning comment

    Hey, I've wanted to read the comment of a request/response object. I'm using Jython and Java8. It's an implementation of a passive scanner, and the way I wanted to access: self._requestResponse.getComment() If I print the result it is always a None value, despite having set a comment on that particular RR. Tried it with putting the comment on the RR in the Proxy tab as well...

  • makeHttpRequest is very slow

    Hi all, I'm writing an extension that aims at sending many requests from multiple sessions of different users. Currently, I'm using callbacks.makeHttpRequest(...) to send requests but that method takes a very long time to finish. My server is local and pretty fast, so communication does't take that much of time. Is there any faster way to replace that method? I'm thinki...

  • JUnit test with Burp Extensions

    Hi, I'm developing a Burp Extension and want to add some testing. Is there a way to create IHttpRequestResponse objects manual? Or retrieve callbacks during a JUnit test, without starting Burp. I do not really know what to do. Thanks for your help!
