Bad Request Youtube something?

THE DREADED "BAD REQUEST" STRIKES AGAIN

If "your browser sent a request that this server could not understand"

and "size of request header field exceeds server limit", your request

is a bad or oversized cookie. (The same thing is true for "Error 400").

For some very strange reason, it seems 9 of

10 Bad Request messages implicate Firefox.

Simply delete your "Cookies" and everything

will be okay. Don't worry about erasing them;

nothing bad will happen. You won't lose your

internet browser's "Bookmarks" or "Favorites".

The worst thing that could happen is you will

be asked to retype your username/password

when you return to YouTube and some other

websites -- that's all.

As you're dumping your cookies, you should

also erase all your "Temporary Internet Files"

and "History". This will render your computer

totally "fresh" in YouTube's eyes. It would be

best if you shutdown / reboot after doing this:

Internet Explorer 6:

→ Tools → Internet Options

→ Delete Cookies → OK

→ Delete Files → OK

→ Clear History → Yes

→ OK

Internet Explorer 7:

→ Tools → Internet Options → Delete...

→ Delete files → Yes

→ Delete cookies → OK

→ Delete history → OK

→ Close (browsing history window)

→ OK

Mozilla Firefox 3:

→ Tools → Clear Private Data

[x] Browsing History

[x] Download History

[x] Saved Form and Search History

[x] Cache

[x] Cookies

→ Clear Private Data Now

Apple Safari 3:

→ Edit → Preferences

→ Security (tab) → Show Cookies

→ Remove All → Done

then afterwards:

→ Safari → Empty Cache → Empty

then afterwards:

→ History → Clear History

If you using Firefox Clear the Cache and Delete the Cookies from site(s) that cause problems:

Tools > Options > Advanced > Network > Offline Storage (Cache): "Clear Now"

Tools > Options > Privacy > Cookies: "Show Cookies"

If clearing the cache and the cookies didn't help then try to rename (or delete) cookies.sqlite (cookies.sqlite.sav), and a possible leftover cookies.txt from Firefox 2, in the Profile Folder in case there is a problem with the file that stores the cookies.

That will remove all the cookies, so try to rename first, then you can undo if it doesn't work.

If renaming the file(s) works then you can delete the no longer needed renamed files.
