Question

I am using mule studio,
and I am trying out examples on it.

When ever i do a HTTP browser request, 2 requests come simultaneously,
in which first one is /favicon.ico and the second request is the actual request.

My configuration XML is as follows.

<?xml version="1.0" encoding="UTF-8"?>

<mule xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns:file="http://www.mulesoft.org/schema/mule/file" xmlns:jms="http://www.mulesoft.org/schema/mule/jms" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation" xmlns:spring="http://www.springframework.org/schema/beans" xmlns:core="http://www.mulesoft.org/schema/mule/core" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="CE-3.2.1" xsi:schemaLocation="

        <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8046" doc:name="HTTP"/>

    </flow>
    <flow name="SampleTest" doc:name="SampleTest">
        <jms:inbound-endpoint queue="BANK1" connector-ref="Active_MQ" doc:name="JMS"/>
        <echo-component doc:name="Echo"/>

        <file:outbound-endpoint path="C:\Documents and Settings\balajik\Desktop" outputPattern="myfile.txt" doc:name="File"/>
    </flow>
</mule>

When ever I do a Http browser request:
lh:8046/manasa-sundarraman

the flow gets executed twice as 2 requests arise.
The requests are :
1) /favicon.ico
2) /manasa-sunderraman

My question is what is that /favicon.ico ?
Why it is coming as a request ?
How to avoid it ?

Answer 1

I found out a way to clear favicon.ico request.
If we add a filter in-between you will be able to filter the favicon.ico request.

<message-filter doc:name="Filter favicon">

<not-filter>

<wildcard-filter pattern="/favicon.ico" caseSensitive="true"/>

</not-filter>

</message-filter>

adding it after echoing the Http request solves the issue
