Hi, There's this bug I noticed that I'm unsure if it's been fixed in later version. When you gzip a XML based MS word document. There's a very high chance that the closing tag of the document "</w:wordDocument>” becomes “</w:wordDocument" and Word will not be able to open the file. I've found that for these documents if we have instead "</w:wordDocument ><" as the closing tag then the '<' key will be removed during compression thus making it valid....but since the last character doesn't always get removed this isn't really practical. By the way if there's already a method for overcoming this bug please let me know. I'm using gzip for C# ASP.NET.
