Having access to your cookies as a developer is crucial but even as a user it might be useful to take a look sometimes.

But what about querying them with sql queries? Picture this: Show me all cookies from localhost and order them by expirydate. No problem, I’ll show you how…

The procedure is simple. We are lucky that Firefox stores its cookies in an Sqlite Database. Therefore we can simply access it with any database client which supports sqlite. Voilá! Our best candidate is the Firefox extension Sqlite-manager. This brilliant tool offers us a nice interface to access our beloved cookies.

1. Install Firefox extension Sqlite-manager
2. Launch it from Firefox (Extras > SQLite Manager)

It loads the cookies.sqlite database by default. Thats great because its exactly what we need. There is a table called moz_cookies which contains our cookies. Now its up to you .. query em’!

I really like the idea of having all my bookmarks online so i can access them from wherever I want and I don’t need to backup them by myself etc. I tried del.icio.us and some others but never was really satisfied because every service missed some feature i’d like to have in such a service.

Must have features:

  • Possibility to group bookmarks in folders
  • Possibility to tag bookmarks
  • search through them
  • make them public or private
  • plugin to access the bookmarks in FF or IE
  • Import/Export your bookmarks

Nice to have features:

  • share them with friends
  • random bookmarks
  • recommended bookmarks

Finally I found the free GPL’d online bookmark service called Chipmark, which actually has all the features mentioned above. I can highly recommend it since I use it every day, in IE and FF. They also started to provide a public webservice API that you can use in your own applications. By now you can login and the get all your folders and links. This might be really usefull for some people.

Wow, that was finally my first article here :-) I hope it is usefull for somebody.

After some testing I realized that somehow the browser is randomly showing a blank (white) page when I hit the reload button a couple of times. The interesting thing was that when I viewed the sourcecode everything was there but the page wasn't displayed at all. I did some research and found the reasons/solutions for it.

Problem: IE7 displays a blank page after doing some refresh's.
Environment: classic ASP application, WIN XP Pro, IIS 5.1
Reproduction: create the following page and refresh it a couple times:

PLAIN TEXT
ASP:
  1. <% response.buffer = true %>
  2. <html>
  3.   <head></head>
  4.   <body>
  5.     <script src="somescript.js"/>
  6.     test, test
  7.   </body>
  8. </html>
  9. <% response.flush() %>

Solution: There are two points I've found out...

  • check if you have any scripts (script src=".."/> loaded within the -tag. If yes then you'll have to move them to the body and everything should work. As far as I remember the W3C says "This element may appear any number of times in the HEAD or BODY of an HTML document." [W3C Script element] Anyway
  • if you are using classic ASP you also need to assure that you don't flush the response at the end of your page. Remove the response.flush() line and your apps should work fine.

Okay now lets move on to the details. I was searching the web and there are hardly any resources for this bug yet. I found a post about it in the MSDN forums (IE 7 display blank page on refresh when viewing session enabled PHP pages served from IIS 6!!) where a guy experienced the same in his PHP apps and I've found a post by a guy called Kerry D. Wong who blogged about a similar issue (Meta Refresh Bug in IE7?) but in my case it did not solved the problem but i came closer.

I have a dozen of apps written in classic ASP and all of them display a blank page from time to time now. Moving the javascript references to the body (solution of the PHP problem above) did not solved the problem in my case but when I removed them completely then everything worked fine. So the bahavior is similar somehow. I played around and finally discovered that it has to do with the response.flush(). When I got rid of that line everything was fine and like in the old days... buuut MS should pay for the time I have spent on this.

Ahm, where should I send the invoice?

As there aren't almost any resources about this bug on the web yet I cannot really tell you the detailed reasons for it but I am sure they will pop up soon. I guess it has something to do with the keep-alive requests. There is a remark about the response.flush() method in the MSDN documentation which says: "If the Flush method is called on an ASP page, the server does not honor Keep-Alive requests for that page.".

However yesterday I had the time to download this new thing and have a try on the new surf experience. Ive just used it for one day now but its awesome till now. On my notebook (old sony vaio) it is much faster than the new Firefox 2.0.

Anyway to get the point I was searching the web for already known bugs especially for web devs. Cause I am sure the next weeks will be full of minor bugfixes in already existing web apps. Here are two lists ive found:

List from Channel 9 on MSDN
Gtalbot.org

Funny that just after the release we already have a "wish" list available which allows us to improve the new "improved" browser

IE.next
