  • Is this a legitimate implementation of a 'remember me' function for my web app?

    - by user246114
    Hi, I'm trying to add a "remember me" feature to my web app to let a user stay logged in between browser restarts. I think I got the bulk of it. I'm using google app engine for the backend which lets me use java servlets. Here is some pseudo-code to demo: public class MyServlet { public void handleRequest() { if (getThreadLocalRequest().getSession().getAttribute("user") != null) { // User already has session running for them. } else { // No session, but check if they chose 'remember me' during // their initial login, if so we can have them 'auto log in' // now. Cookie[] cookies = getThreadLocalRequest().getCookies(); if (cookies.find("rememberMePlz").exists()) { // The value of this cookie is the cookie id, which is a // unique string that is in no way based upon the user's // name/email/id, and is hard to randomly generate. String cookieid = cookies.find("rememberMePlz").value(); // Get the user object associated with this cookie id from // the data store, would probably be a two-step process like: // // select * from cookies where cookieid = 'cookieid'; // select * from users where userid = 'userid fetched from above select'; User user = DataStore.getUserByCookieId(cookieid); if (user != null) { // Start session for them. getThreadLocalRequest().getSession() .setAttribute("user", user); } else { // Either couldn't find a matching cookie with the // supplied id, or maybe we expired the cookie on // our side or blocked it. } } } } } // On first login, if user wanted us to remember them, we'd generate // an instance of this object for them in the data store. We send the // cookieid value down to the client and they persist it on their side // in the "rememberMePlz" cookie. public class CookieLong { private String mCookieId; private String mUserId; private long mExpirationDate; } Alright, this all makes sense. The only frightening thing is what happens if someone finds out the value of the cookie? A malicious individual could set that cookie in their browser and access my site, and essentially be logged in as the user associated with it! On the same note, I guess this is why the cookie ids must be difficult to randomly generate, because a malicious user doesn't have to steal someone's cookie - they could just randomly assign cookie values and start logging in as whichever user happens to be associated with that cookie, if any, right? Scary stuff, I feel like I should at least include the username in the client cookie such that when it presents itself to the server, I won't auto-login unless the username+cookieid match in the DataStore. Any comments would be great, I'm new to this and trying to figure out a best practice. I'm not writing a site which contains any sensitive personal information, but I'd like to minimize any potential for abuse all the same, Thanks

    When python raise an exception in the middle of a pygtk signal handling callback, the exception is catched by the gtk main loop, its value printed and the main loop just continue, ignoring it.

  • MySQL: automatic rollback on transaction failure

    - by praksant
    Is there any way to set MySQL to rollback any transaction on first error/warning automatically? Now if everything goes well, it commits, but on failure it leaves transaction open and on another start of transaction it commits incomplete changes from failed transaction. (I'm executing queries from php, but i don't want to check in php for failure, as it would make more calls between mysql server and webserver.) Thank you

  • Web application starter kit

    - by Steve Robillard
    I am looking for a site that allows you to input a project name, choose a doctype, a js library etc. and then generates the directory structure and files to start a web project. I know about project deploy, but it is no longer maintained. There was a new one that was created within the last 2 or 3 months, but for the life of me I can't find it either through Google nor my delicious bookmarks. Any help would be greatly appreciated. Thanks, Steve

  • Integrating PayMill: The token filled input field is not created, error "field_invalid_amount"

    - by automatix
    I'm implementing the Credit Card Payment form of PayMill according to the Payment Form docu. So I copied the JS from the Bridge docu page and the form from the Payment Form docu page. But no token is created. When I try to debug the JS and add console.info(error.apierror); into the paymillResponseHandler(...) function, I get the error code: field_invalid_amount. According to the support page There are three possible reasons for this error message: no amount value was provided numbers were rounded wrong delimiter symbol But the amuont is provided and I've already tried different delimiter symbols. What "numbers were rounded" means, is not clear. What can be the problem and how to fix this issue?

  • WCF wrapper COM object

    - by LarryR
    I have a third party COM component (they don't offer a .Net assy), that has the additional feature that it only works under x86 compile. I am trying to wrap this in a WCF service, but if I select x86, the service won't start (System.BadImageFormatException). Any workarounds for this ? Thanks Larry

  • Clamping a vector to a minimum and maximum?

    - by user146780
    I came accross this: t = Clamp(t/d, 0, 1) but I'm not sure how to perform this operation on a vector. What are the steps to clamp a vector if one was writing their own vector implementation? Thanks clamp clamping a vector to a minimum and a maximum ex: pc = # the point you are coloring now p0 = # start point p1 = # end point v = p1 - p0 d = Length(v) v = Normalize(v) # or Scale(v, 1/d) v0 = pc - p0 t = Dot(v0, v) t = Clamp(t/d, 0, 1) color = (start_color * t) + (end_color * (1 - t))
