SearchCitation.asp and related search pages (other criteria) return a page indicating that a citation was not found. The same result occurs with FireFox. IE 5 under Classic produces valid results.
Setting the User Agent to Windows IE 6.0 does not alter the results.
Per info "Microsoft Internet Explorer is required for use on this site. Other browsers are not supported at this time." [https://www.sanmateocourt.org/traffic/Default.asp] I confirm the bug.
I've checked the reported site in WebKit 4.0.4 (6531.21.10, r50918) today and found that the original reported site no longer exist. San Mateo Traffic is located now in this URL: https://www.sanmateocourt.org/traffic/
I've tried to reproduce the reported problem and I found that the site seems to work now correctly.
I close this bug as resolved fixed an evangelism bug.
Alex feel free to reopen this report if you find problem with this page now.
