Content encoding problems when searching from Google Search Box #86

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. If the browser is set to send the "accept-encoding: gzip, deflate" 
header, search box fails to display results

FireFox will display a content-encoding error whereas IE does not display 
anything and you get a blank screen

What is the expected output? 
Search results should be displayed

What do you see instead?

If the verbose level logs are enabled, you can see the following exception 
messages in the Event Viewer-->Application logs with 'Source' name as 
'Google Search Box for SharePoint':
"Unable to load the GSA result"

This is followed by the following stacktrace:

"Exception while applying transformations to GSA results: '', hexadecimal 
value 0x1F, is an invalid character. Line 1, position 1.
Stack Trace:    at System.Xml.XmlTextReaderImpl.Throw(Exception e)
   at System.Xml.XmlTextReaderImpl.Throw(String res, String[] args)
   at System.Xml.XmlTextReaderImpl.ThrowInvalidChar(Int32 pos, Char 
invChar)
   at System.Xml.XmlTextReaderImpl.ParseRootLevelWhitespace()
   at System.Xml.XmlTextReaderImpl.ParseDocumentContent()
   at System.Xml.XmlTextReaderImpl.Read()
   at System.Xml.XmlTextReader.Read()
   at System.Xml.XPath.XPathDocument.LoadFromReader(XmlReader reader, 
XmlSpace space)
   at System.Xml.XPath.XPathDocument..ctor(XmlReader reader)
   at ASP._layouts_searchresults_aspx.GoogleSearchBox.transform(String 
XMLPage, XslTransform xslt)
   at ASP._layouts_searchresults_aspx.__RenderSearchSummary(HtmlTextWriter 
__w, Control parameterContainer)"

The above messages are shown only when the stylesheet option is set to "Use 
local stylesheet"

If the stylesheet option is set to "Use Search Appliance's front End" no 
error messages are available in the logs and no result is displayed

Suggested work-arounds:

With Firefox disable the accept-encoding header. Follow these steps for the 
same:

1. Open the Firefox browser
2. On the address bar, type about:config
3. In filter section type "Network.http.accept-encoding"
4. By default this is set to gzip,deflate
5. delete the value of this entry

For Internet Explorer follow these steps:

1.Open IE browser
2.Go to Tools->Internet options
3.Open Connections Tab
4.Click on “LAN settings”
5.Select option “Automatically detect settings”.

This is related to the browser settings. One needs to apply correct browser 
settings 
as mentioned above and the same code will work.

The steps given for IE don't seem to work. What has LAN Settings got to do with 
Accept-
Encoding: gzip,deflate?

I think we are doing an unzip in one case in the SearchResults page. Will that 
not 
help?

If it is not possible to unzip from within code, we must not send the header 
Accept-
Encoding: gzip,deflate to the GSA. I couldn't find an acceptable way to disable 
Accept-
Encoding: gzip,deflate in IE. The only way is to disable HTTP 1.1 which is 
unacceptable.
