[SOLVED] Eclipse Helios/Galileo Update sites cannot be accessed on Windows machine with IE7

Eclipse Helios/Galileo Update sites cannot be accessed on Windows machine with IE7

When starting the update, the following error is displayed:

Network connection problems encountered during search. Unable to access "http://download.eclipse.org/releases/helios". Error accessing site stream. [Server returned HTTP response code: 503 for URL: http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd] Server returned HTTP response code: 503 for URL: http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd Error accessing site stream. [Server returned HTTP response code: 503 for URL: http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd] Server returned HTTP response code: 503 for URL: http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd

As described at

http://www.w3.org/blog/systeam/2008/02/08/w3c_s_excessive_dtd_traffic http://www.outofcontrol.ca/2009/02/20/w3org-dtdxhtml1-strictdtd-blocks-windows-ie-users/

w3.org blocks IE calls to http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd (as it is loading it much too frequently). I was able to load the DTD by setting a different UserAgent for IE7 using

%windir%\System32\cmd.exe /k %windir%\System32\reg.exe ADD "HKLM\Software\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent" /v Version /d "Opera/9.2.1" /f

I tried to -D overrides suggested at:

Change user agent in Eclipse 3.5 for new software installations

to no avail. I think eclipse does not follow the User-Agent set by IE7 ...

Is there an other way to override the User-Agent for Eclipse?

Thanks
