Header Or Cookie Too Large

I have been using a site called DS Summit for many years. I started using the avast browser and all was well for a time. Suddenly I start getting the following message: “400 Bad Request
Request Header Or Cookie Too Large”
In the past, I could google the site, delete my shortcut, make a new one and it worked again. Occasionally it would occur again.
At present though, adding a new shortcut does not work because avast will not let me access the site from google anymore. I can however access it from other browsers. Below is the info requested from the FAQ page.

Your reply means absolutely nothing to me. I am not a computer geek but, I can get around. I do however, need some instructions, like “go here”, “click this”, “delete this” or something other than a link to the forum. The site I am trying to access is: http://new.dxsummit.fi/#/?include=HF&exclude=3.5MHz,1.8MHz,5MHz&exclude_modes=CW,DIGI&include_modes=PHONE

Asyn is saying post this in the Avast Secure Browser sub-forum where it is likely to get seen by others using ASB and or a member of the Avast Team.

That said, a search for the error message you are getting returns many hits on different browsers (not necessarily ASB) so there could be a change at the site that results in this error. I don’t use it so I can’t test it, but I am able to visit using Firefox 88.0.

https://www.google.co.uk/search?q=“400+Bad+Request+Request+Header+Or+Cookie+Too+Large”

Thank you for deciphering it for me. The problem is limited to ASB because I can get to the site from other browsers. I am starting to think it is not worth the trouble if I have to post to forums and HOPE someone has an answer. It is just easier to dump ASB for another browser. Thanks again.

I just went to the ASB menu and clicked on “More tools” “Privacy Cleaner” and deleted 4 weeks of cookies. It seems there is a limit to how many cookies this browser can eat. Maybe a little milk will help it in the future. :wink:

You’re welcome.

As far as cookies go there are settings in most browsers that will clear Cookies and Site Data, etc. when the browser is closed. That is how I have Firefox set up, but I don’t close it every day. Periodically I do clear it as I see no worth in storing this data indefinitely.
