Hi all,
I have a strange behavior in my web app.
Let's say I have this URL which redirect to products page to display items:
http://abc.com/page.aspx?cId=c-017&cname=Remote%20Start%20and%20Security&SubId=RemoteStartNSecurity4&SubName=Remote%20Starters[^]

Sometimes this URL changes to the below one and adding these characters ('A=0 )
http://www.abc.com/page.aspx?cId=c-017&cname=Remote Start and Security&SubId=RemoteStartNSecurity4'A=0&SubName=Remote Starters

And of course get an error from products page.
Does anyone know the reason why the URL is adding these characters or why it's changing?

Thank you
Samira

Because you have code somewhere doing it. You'll have to debug it to find it.

Not enough information. To start, learn URL encoding, if you haven't done it before.

Solution 1

In the second url, just before A=0 there is a single quote. It most likely is preventing encoding of the url completely. I would check out where and why the single quote is added.

Good luck!
