barryhunter, I see what Wooble said. I am a visitor of http://admins.googleapps.com/ I open this site with Firefox browser and input error|400 into the search box which located in top right of screen, and press the Search Site button to submit this query, and I got a response of: Your search for error|400 did not match any pages. Everything work fine, and I want to share this page(search result page) to my friend, so copy the url from address box and send to my friend: http://admins.googleapps.com/system/app/pages/search?q=%22error|400%22 Now, suppose you are my friend, and got this url and paste it back to IE or Firefox, to see the result Until now, what's wrong with Vistor, Firefox or admins.googleapps.com???

Firefox will send your URL exactly as you enter it, yes. But if you fill out a form (such as a search box) in Firefox, it will correctly URL-escape the | character for the URL. Internet Explorer behaves in the same manner, so any URL generated by a form will have the | character correctly escaped.

The RFC is clear as to what characters are acceptable in the query string part of a HTTP URL. | is not one of these characters, so if your browser is sending one, it's an issue either with your browser or with your URL encoding. -Nick Johnson --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

By this definition, you are claiming that the main google.com search server is wrong, because it does not refuse to accept raw pipe characters. Certainly, one set of Google servers are wrong, because there are two different behaviours. Here's a schizophrenic Google server for you, this very site: http://groups.google.com/group/google-appengine/browse_thread/thread/4ced9847935e7b34 Type: this|that into the search box in the upper right hand corner, and click Search this group. It panics and redirects you to the main page at http://groups.google.com. You search query is lost. Try it again, but this time click on Search groups. This works -- results are shown. The pipe was not encoded by my Firefox 3..0.x browser. The RFC is clear as to what characters are acceptable in the query string part of a HTTP URL. | is not one of these characters, It is clear, but it also gives reasons why: Unsafe: Characters can be unsafe for a number of reasons. The space character is unsafe because significant spaces may disappear and insignificant spaces may be introduced when URLs are transcribed or typeset or subjected to the treatment of word-processing programs. The characters and are unsafe because they are used as the delimiters around URLs in free text; the quote mark () is used to delimit URLs in some systems. The character # is unsafe and should always be encoded because it is used in World Wide Web and in other systems to delimit a URL from a fragment/anchor identifier that might follow it. The character % is unsafe because it is used for encodings of other characters. Other characters are unsafe because gateways and other transport agents are known to sometimes modify such characters. NONE of this applies once the URL has reached the web server. Why insist that the browser send you a %7c instead of | when you're just going to immediately decode it to | anyway? google.com doesn't. The google groups server is borked whatever you do. Here's the search with an explicit %7c: http://groups.google.com/group/google-appengine/search?group=google-appengineq=this%7cthatqt_g=Search+this+group so if your browser is sending one, it's an issue either with your browser or with your URL encoding. When millions of people browse with Firefox and Google Chrome, which do not encode '|' when an ordinary user types it into a search box, and your server software fails inelegantly to handle it, the fault is with the server software. That's why the main google.com software gets it right, and the groups.google.com software, among other Google services, gets it wrong... --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

Like others general visitors, I often copy a url from address box and share to friends If you submit a search by click 'Search' button, Firefox will escape '|' to '%7c' and send to Web Server, but it will keep '|' remain in the address box If you paste 'error%7C400' to Firefox and press enter to submit, Firefox will convert '7%C' to '|', you will see 'error|400' in the address box, why??? I found that those server named 'GFE 1.3/2.0' can not accept the '|' char, but GWS or 'Google Frontend' does, so I guess GFE's real name is 'Google Firewall Edge', a firewall must be fast and secure, means it has been simplified or lightweighted? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.
