  IIS Log encoding for ANSI non-English codepage Reply Contact Hi there, Recently I migrate website from IIS 6 to IIS 7, everything goes well but 1 thing. The non-English ANSI Characters in IIS log appears like ?????? I try with ASP and ASP.Net and both integrated and class app pools with following links: http://localhost/test/test.asp?kw=中文測試 http://localhost/test/test.aspx?kw=中文測試 In IIS log both requests cs-uri-stem are kw=???????? I also try to change log encoding from UTF-8 to ANSI, but no luck. How can I set up IIS log to store these non-English ANSI characters? Thanks.  - Robert Hu ps:  It is not cs-uri-stem, it is cs-uri-query not proper encoded.

Mm.. so why query string not encoded? Cheers, Bernard Cheah

  Re: IIS Log encoding for ANSI non-English codepage Reply Contact . anilr: Did you even read my post?  I took a netmon trace of the packet on the wire and IE is sending ????'s in the query-string.  Have you tested vista/ws08 client against IIS6 or ws03/xp client against IIS7?   I did read your post and you didn't get my meaning. The same client machine (Vista+IE7) can send same request to IIS 6 and IIS 6 log the non-English characters correctly. So I believe it doesn't the client issue. If you follow the thread you can see qbernard's post mention this issue happened to Simplified-Chinese too. This issue could effect the adoption of Windows 2008/IIS 7 in non-English world, which I believe is bigger than English world. If you are from IIS team, you should test and answer why IIS 7 cannot log non-characters in log correctly and not challenge why we don't use vista or xp as client

  Re: IIS Log encoding for ANSI non-English codepage Reply Contact I do more testes to clarify the issue. Here is the code in both ASP and ASP.Net <% Response.Write(Request("kw")) %> Here are the request for ASP and ASP.Net http://localhost/test.asp?kw=中文測試 http://localhost/test.aspx?kw=中文測試 Here are the results: 1. ASP: ASP doesn't have display issue, it can display Chinese Characters correntcly 2. ASP.Net By default setting (.Net Globalization = UTF8, App Pool in Integrated Mode) ASP.Net can not display Chinese characters: After changing App Pool from Integrated to classic and .Net Globalization requests encoding from UTF-8 to big5, the Chinese characters display correctly But in both cases neigher correctly log cs-uri-query in log files   Conclusion: There are some encoding issue in ASP.Net in integrated app pool and IIS Log. Hope these testes can help IIS team to figure out what goes wrong.

  Re: IIS Log encoding for ANSI non-English codepage Reply Contact The integrated mode asp.net issue is an asp.net bug discussed here which will be fixed in the next asp.net service pack. As for the original logging issue - can you give me the exact bytes of the url you are requesting?  I am unable to get IE to send a url with unicode characters if I just cut and paste the url from your post.

  Re: IIS Log encoding for ANSI non-English codepage Reply Contact Probably not, clearly roberthu has gotten IE to send the unicode characters to IIS since his asp page echoes it back correctly - I have not been able to do it when I cut-n-paste the characters from this webpage into IE - maybe some problem with cut-n-paste. So, I still need to set up a repro.  Peter huang did send me the exact unicode hex digits for this repro in a separate e-mail - I just need to give it a try.
