title: What is apache's maximum url length?
body: <p>What is the maximum length of a URL in apache? Where is it documented, and is it configurable?</p>
  
  <p>I'm implementing an openid identity provider, and would like to know the limitations I'm up against. I know about the 2048 byte path limit on Internet Explorer. That can be handled specially using user agent detection. Other browsers have much higher URL limits. </p>
  
  <p>So what I'm interested in is apache server limits when coding an application. </p>
