HTTP Request Corruption

Question

On a site that receives a very high amount of traffic some small percent of requests come like this:

http://cheezburger.com/ScriptResource.axd?d=zaVpgH63ePt90pn</a>                                                   <br />                        <br />                        <p>                            <a id=

On the page referrer page there is a line like so:

<script src="/ScriptResource.axd?d=zaVpgH63ePt90p8fuEYkPAKFZuziMYsiIUbmxDb-gQ23Cx78LNJNFXTqKciA4ND_frR-_r9UKsdtLPk6M08xyk6cXFSLUrbBGDlvPIf-F9w1&amp;t=ffffffffd5e08dd5" type="text/javascript"></script>

and another couple lines much further on:

    <a id="login_LoginState_LoginButton" class="button1" UseSubmitBehavior="false" href="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;login$LoginState$LoginButton&quot;, &quot;&quot;, true, &quot;ctl00$Login1&quot;, &quot;&quot;, false, true))">Log In</a>
<br /> 
<br /> 
<p> 
    <a id="login_LoginState_PasswordRecoveryLink" href="/forgot.aspx">Forgot Password?</a> 

So it appears that part of the page has been removed. It appears to happen more often in IE than Firefox, but that might be because we have more IE traffic than FireFox. We have HTTP compression turned on, but I don't know if that is the problem.

So my question is what is going on and how can it be fixed?

Answer 1

After looking at the automatic bug reports generated by this error, it seems the majority of the cases where this occurs is with clients going through proxies. I think this comes down to either a bug in the proxy or a bug in the gzip implementation on the proxy.
